Both 3003 and 3004 belong to the group of <strong>food grade
aluminum sheet</strong>. 3003 is usually used in cookware, and 3004 is more frequently in food packaging in foil sheet form. However, there are also circles of 3004 and foil rolls of 3003, since the two share a lot in composition and properties. The main difference between 3003 and 3004 is that 3004 contains magnesium element and 3003 does not. The metal of magnesium is light, soft and silvery white, featured by strong anti-corrosion performance and flexibility. As a result, 3004 is softer and more corrosion resistant.<br></p>

3003 aluminum circle is a common raw material for cookware. Aluminum is a metal with excellent thermal conductivity. It will not rust and is resistant to many forms of corrosion. Since 1965, indirect evidence has linked Alzheimer's disease with aluminum, but so far there has been no evidence that aluminum is involved in the disease. There are three kinds of aluminum dick circles by surface treatment methods: stretching, die casting or anodizing. Stretched aluminum is generally made of
aluminum alloy with magnesium, copper or bronze to increase strength. The die-cast aluminum disc is thick and suitable for soup pots. However, the cookware made of ordinary surface-treated aluminum wafers is not suitable for cooking acidic foods, because these foods will be oxidized on the surface of the aluminum pan. The anodized aluminum discs solve this problem, and their surface performance is very stable. they can be used as a juice pot, chowder, roasting pot, etc.</p>

aluminum foil is used in food packaging, food container
aluminum foil container foil and flexible packaging
aluminum foil. The statuses of our <strong>aluminum container foil </strong>are O, H18, H22, H24, etc. The main specifications are 80-1500 mm wide and 6-200 microns thick. The advantages of Haomei in
aluminum foil are thickness control and oil control. Both are crucial in food grade
aluminium foil sheet production. As the thickness of the aluminum box decreases, its trace conditions can affect the temperature, oil film, oil and gas concentration, etc. A roll of
aluminum foil can reach hundreds of thousands of meters, and the rolling time is as long as about 10h. Errors in thickness measurement with time extend easily. Therefore, to truly control the thickness difference of the aluminum box within 3%, many conditions need to be used to ensure: use of
aluminum foil blanks of acceptable thickness; adjustment and control of the reduction and roll shape during rolling, the grinding of the rollers according to the specified parameters and so on.</p>
