3003 aluminum pipe
3003 aluminum pipes are mainly used to require high plasticity and good welding properties. Low load parts working in liquid or gas media, such as gasoline or lubricating pipelines, various liquid containers, and other small load parts made of deep -pulpated loading parts with deep -pulpated loading parts. , Wiring for rivets.
State: O, H112, H14, H24
Characteristic
3003 is Al-Mn alloy, which is the most widely used rust-proof aluminum. This alloy is not high (slightly higher than the industrial pure aluminum), and it cannot be treated with heat treatment. Therefore, it is used to improve its mechanical performance: There is a high plasticity in the annealing state. When the semi -cold sclerosis is still good, the plasticity is low when the cold is harden, good corrosion resistance, good welding, poor cutting performance
Use
3003 aluminum tube formability, dissolution, and corrosion resistance are good. It requires good forming performance, high corrosion -weldable parts, or requires both these properties and requires high -strength work than 1xxx. Storage device, tanks and tanks of liquid products, various pressure vessels and pipelines, heat sinks, cosmetics, photocopic drums, and ship materials for various pressure vessels and pipelines.
