7003 aluminum bar has excellent welding performance and elastic resistance, good processing and formability, good thermal deformation ability and processing performance, high strength can be obtained after artificial aging heat treatment, and good welding performance. 7003 aluminum bar is widely used for gun mounts and armored structures. 7003 aluminum bar is used for refrigerated containers, cryogenic equipment and storage boxes, fire-fighting pressure equipment, equipment, armor plates, and missile devices.
7003 aluminum bar usually have such types in production: 7003 aluminum round bar, 7003 aluminum square bar, 7003 aluminum flat bar, 7003 aluminum hexagon bar and 7003 aluminum angle bar.
Product advantages of 7003 aluminum bar:
Chalco aluminum bar produces are widely used in aviation, construction, automotive--these three major areas, high precision, small coarse crystal, uniform oxidation, good straightness, high turning performance, small grain size and moderate price, short delivery, all these prove us as the top of the world.
- Accuracy:+/-0.02mm
Purpose: to guarantee the automatic processing of high precision machining parts.
- Straightness <0.3m/2.5m
Purpose: Guarantee the speed requirements>8000 rpm, no material jittery.
- Coarse crystal ring<0.5mm
Purpose: To reduce the amount of turning by the customer, improve efficiency and reduce costs.
- Grain control
Purpose: to ensure that the 2、5、6、7 series aluminum alloy in the hard anodizing, anodizing uniform, color bright and beautiful.
- Turning performance improvement
To improve the processing of uniform chip, improve the processing of yards yield.
