6061 aluminum bar is a high-quality aluminum alloy product that has undergone heat treatment and pre-stretching process; although its strength is not comparable to that of 2XXX series and 7XXX series, its magnesium and silicon alloy characteristics are many, with excellent processing performance and excellent welding characteristics And electroplating, good corrosion resistance, high toughness and no deformation after processing, compact material without defects and easy to polish, easy to color film, excellent oxidation effect and other excellent characteristics.
Representative uses of 6061 aluminum bar include aerospace fixtures, electrical fixtures, and communications. It is also widely used in automated mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, PC board solder carriers, etc.
6061 aluminum bar often have such types: 6061 aluminum round bar, 6061 aluminum square bar, 6061 aluminum flat bar, 6061 aluminum hexagon bar and 6061 aluminum angle bar.
Product advantages of 6061 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.
