The 7075 aluminum sheet is a high-strength aluminum alloy with higher hardness among the heat-treatable aluminum alloys. It is widely used for high-strength mechanical parts, hardware products, molds, auto parts, aerospace and other fields. This article will briefly introduce the three major factors that affect the aging strengthening of 7075 aluminum plate.1. The volume of the dissolved phase. In general, if other conditions are the same, the larger the volume fraction (f) of the dissolved phase, the higher the strength. Alloys with large f-values require large solid solubility at high temperatures, and the composition and process for obtaining high solid solubility can usually be determined by the phase diagram.2. The dispersion degree of the second phase particle. Generally speaking, the equilibrium desolvation phase is not coherent with the matrix, the interface energy is relatively high, the critical size of nucleation is large, and the driving force for grain growth is also large, and it is not easy to obtain highly dispersed particles.Therefore, the formation of GP zone and coherent or partially coherent transition phase can make the alloy obtain high strength. Generally, in order to effectively strengthen the alloy, the distance between the dissolved phases should be less than 1um.3. The resistance of the dissolving phase particles to dislocations. A large degree of mismatch causes a large strain field, which is beneficial to strengthening; high interface energy or antiphase domain boundary energy is also beneficial to strengthening.As a big 7075 aluminum plate supplier, Haomei Aluminum can offer you 7075 aluminium sheet with different tempers.

6061 and 7075 aluminum sheet are two common aluminum alloys and widely used. There are an analysis of their chemical element, mechanical properties, processing performance and price.1. Chemical ElementAlloySiFeCuMnMgCrZnZrTiAl60610.4-0.80.70.15-0.40.150.8-1.20.100.10-0.10Remainder70750.40.51.2-2.00.302.1-2.90.18-0.285.1-6.10.050.20RemainderThe main trace elements of 6061 aluminum plate are Mg and Si, forming the Mg2Si. A small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing its corrosion resistance.7075 aluminum plate has high content of trace elements. The main element is zinc that forms Al-Zn-Mg-Cu with the addition of copper and magnesium.2. Mechanical properties7075 aluminum plate is well known as aircraft aluminum,which is very superior in mechanical properties. 7075-T6 is currently the highest strength aluminum alloy, which is better than ordinary steel.In industrial manufacturing, it is often used in occasions with higher standards, and its advantages are self-evident. Not only the degree of precision is higher, but the service life is longer.In consumer electronics, Apple uses 7-series aluminum sheet for the middle and back covers of iPhone phones. The Apple computer casing is also made of all 7-series aluminum alloys. Other smart phone manufacturers such as OPPO and Xiaomi also uses 7075 aluminum plate.In Equipment materials: In many special fields, it has an irreplaceable advantage. For example, ski poles and golf heads need to withstand the impact of external forces repeatedly, so 7075 aircraft aluminum sheet is more preferred.At present, more and more fields are trying to use aircraft aluminum sheet to improve the appearance and performance of products to achieve differentiation from competing products.3. Processing PerformanceIn terms of machinability, both can be milled well on CNC machine tools.6061 aluminum sheet can be welded, but 7075 aluminum plate is difficult to weld.6061 aluminum is suitable for the surface treatment such as anodizing or coloring. 7075 has unstable anodizing effect.Without further processing, 6061 aluminum alloy has better corrosion resistance.Both 6061-T6 and 7075-T6 aluminum plate is of high hardness, which cannot be bent.4. Price differenceGenerally speaking, the 7075 aluminum sheet price is about 20-40% more expensive than 6061 aluminum plate.In conclusion, In most cases, 7075 aluminum plate is indeed superior to 6061 aluminum plate. But we can't simply draw conclusions that 7075aluminum must be better. We still need to consider the uses and the budget.In general, 6061 aluminum sheet can basically meet the general industrial manufacturing requirements. And 7075 is used in demanding occasions, such as aerospace, military products, precision equipment, high-end electronic equipment,etc. As an aluminium sheet supplier, we have both 6061 and 7075 aluminum plate.

The blister packaging of medicines is made up of PTP aluminum foil, PVC, printing inks, protective agents, adhesives, etc. For pharmaceutical packaging, aluminum foil is the only metal packaging material.As a printing material, PTP foil is non-toxic, odorless, of excellent electrical conductivity, light-shielding properties, extremely high moisture resistance, gas barrier properties and taste retention properties, which is a packaging material that has not yet been replaced.Theoretically the perfect aluminum foil can completely block any gas, water vapor and light, but in fact, due to the rolling process used in the production of aluminum foil, the quality of the rolling oil, the surface condition of the rolling roll and the processing environment, the various defects will inevitably appear.Pinholes are the most serious defects. The size and quantity of pinholes are one of the important metrics to measure the quality of the medical aluminum foil. How to improve the quality of aluminum foil and reduce the number and size of aluminum foil pinholes is an urgent problem for domestic aluminum foil manufacturers to solve.To ensure the PTP aluminum foil, we have to inspect the pinholes of the finished medical aluminum foil. The method is: use a pinhole inspection table. Take 20 pieces of aluminum foil with the size of 400 mm × 250 mm and place them on the pinhole inspection table one by one, and check the pinholes in the dark.The requirements for pinholes are: there should be no dense, continuous and periodic pinholes, and no pinholes with a diameter greater than 0.3 mm. There should be no more than 1 pinholes per square meter.In addition, it is necessary to sample the rupture strength value of the aluminum foil. The testing instrument uses a rupture strength meter. The method is to take three pieces of 40 mm X 40 mm samples from the finished aluminum foil and put them into the gap of the instrument, turn on the oil pump and measure the pressure gauge. The rupture strength value should be greater than 98kpa.In the ptp aluminum foil market, Haomei Aluminum, a bigaluminum foil jumbo roll manufacturer, can offer you 8011, 8021, 8079, 1060,etc., medicine aluminum foil with superior quality.

You may not know that the original packaging materials for medicines are plastic and paper, but these packaging is not easy to store, and easy to destroy the ingredients of the medicine, greatly reducing the efficacy of the medicine. After continuous research and improvement, aluminum foil is finally used for the pharmaceutical packaging.In our daily life, the application of PTP aluminum foil is very extensive and mature. The main uses of medicinal foil are blister packaging of medicine capsules and tablets, and bag-like packaging of powder granules and liquids. Because of its direct contact with edible drugs, each country has very strict requirements on the appearance and performance of ptp foil.The common pharmaceutical aluminum foils have two kinds: 8011 and 8021 aluminum foil. The 8011 aluminum foil thickness is below 0.05mm and 8021 aluminum foil thickness is above 0.05 mm. Generally speaking, the main aluminum foil production process is billet inspection-billet rolling-open middle sub-rolling-coil rolling-finished product-slitting-furnace annealing-finished product packaging.The surface of medicinal aluminum foil requires no oil stains, no shiny, no black lines, no pinholes, no maculas, no ruffles, etc. More importantly, it should be non-toxic, tasteless, safe and hygienic. It needs to be of strong mechanical properties, high blast resistance, strong puncture and tear resistance.To reach these requirements, Haomei Aluminum,an experienced aluminum foil producer, optimizes aluminum ingot and adopt advanced production equipment, and strictly control the product shape. In the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the medicated foil to ensure clean degreasing.
