Aluminum CNC Milling Parts Aluminum alloys have good strength-to-weight ratio, high thermal and electrical conductivity, low density and natural corrosion resistance. Aluminum machined parts can be treated by anodizing (in different colors) and hard anodi
We supply CZ purlin roll forming machine with many years of production experience.When we change from c purlin to z purlin, you only need direction of the rollers to be changed.
The high percentage of nickel maintains an austenitic structure so that the alloy is ductile. The nickel content also contributes resistance to scaling, general corrosion, and stress-corrosion cracking.
