Aluminium alloy is a commonly used industrial material. It is very light and weighs about one-third of the same volume of copper or steel. It is corrosion-resistant, is an excellent conductor of heat and electricity, reflects light and radiant heat, is non-magnetic, is not easy to absorb neutrons, can be safely used in food and medicine. And it can be formed into various kinds of industrial materials by all known metal processing techniques. Such as aluminium tube,
aluminium circle,
aluminium sheet, aluminium foil, aluminium coil, aluminium strip, etc. This article will introduce several common aluminium alloy processing techniques.
(1) Classified according to the force and deformation mode of the product
A. Rolling
Rolling is a deformation process in which the ingot is drawn into the rotating rolls by friction, and with the pressure applied by the rolls, the cross-section is reduced, the shape changes, the thickness becomes thinner and the length increases. According to the different rotation directions of the rolls, rolling can be divided into longitudinal rolling, cross rolling and skew rolling.
During longitudinal rolling, the direction of rotation of the work rolls is opposite, and the longitudinal axis of the rolled piece is perpendicular to the axis of the roll. It is the most commonly used method in flat roll rolling of aluminium alloy plates, strips, and foils.
longitudinal rolling
During cross rolling, the direction of rotation is the same, and the longitudinal axis of the rolling piece is parallel to the axis of the roll, which is rarely used in the rolling of aluminium alloy plate and strip.
Cross rolling
During skew rolling, the rotation direction of the work roll is the same, and the longitudinal axis of the rolling piece is in a certain direction slope. In the production of aluminium alloy pipes and some special-shaped products, two-roll or multi-roll skew-rolling is often used. According to different roll systems, aluminium alloy rolling can be divided into two-roll rolling, multi-roll rolling and special roll rolling (such as planetary rolling, V-shaped rolling, etc.) rolling: according to different roll shapes, aluminium alloy rolling can be divided into flat roll rolling and grooved roll rolling. According to different product varieties, aluminium alloy rolling can be divided into plate, strip, foil rolling, bar, flat bar and special-shaped section rolling, pipe and hollow section rolling, etc.
4. Aluminium tube supplier recommendation
The quality of aluminium tube suppliers on the market is uneven, and the quality and price of aluminium tubes cannot be guaranteed. CHAL Aluminium Corporation is one of the leading aluminium tube suppliers in China. Its products are widely used in the automotive industry, construction industry, HAVC&R and heat transfer industry, aviation, railway transportation, marine industry, etc. Our main aluminium tubes include the following:
