7022 aluminum bar has good forming performance, corrosion resistance, weldability, fatigue strength, and medium static strength. It is generally used for fuel tanks, related, and sheet metal parts of transportation vehicles and ships, instrument street lamp brackets, and refrigeration Installation, TV tower, drilling equipment, rivet wire, etc.
7022 aluminum bar could be extruded in those types: 7022 aluminum round bar, 7022 aluminum square bar, 7022 aluminum flat bar, 7022 aluminum hexagon bar and 7022 aluminum angle bar.
Product advantages of 7022 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.
