2024 rectangular aluminum flat bar has high mechanical properties and excellent resistance to fatigue. During machining, it creates quite long chips, therefore it is not well suited for automatic lathes.
Product advantages of 2024 rectangular aluminum flat bar:
1. Accuracy:+/-0.02mm
Purpose: to guarantee the automatic processing of high precision machining parts.
2. Straightness <0.3m/2.5m
Purpose: Guarantee the speed requirements>8000 rpm, no material jittery.
3. Coarse crystal ring<0.5mm
Purpose: To reduce the amount of turning by the customer, improve efficiency and reduce costs.
4. Grain control
Purpose: to ensure that the 2、5、6、7 series aluminum alloy in the hard anodizing, anodizing uniform, color bright and beautiful.
5. Turning performance improvement
To improve the processing of uniform chip, improve the processing of yards yield.
Chalco Aluminium stocks a variety of aluminum alloy bars (rods) grades and sizes tailored to your needs and specifications.
