Why choose ABRAFIL CuAl8Ni6?
-
Very high mechanical strength and wear resistance:
ABRAFIL CuAl8Ni6 offers excellent resistance to abrasion, impact, friction and fatigue, making it an excellent choice for parts in motion, under load, or subject to intense mechanical stress. -
Excellent corrosion resistance, even in seawater:
Thanks to its composition, this alloy is highly resistant to salt, marine and industrial corrosion, including prolonged immersion. It is ideal for structural or functional parts in marine environments. -
Very good resistance to high temperatures:
The deposited metal retains its mechanical and structural properties when hot, making it suitable for parts exposed to repeated or prolonged temperature rises (brakes, friction parts, etc.). -
Stable metallurgy with low risk of cracking:
ABRAFIL CuAl8Ni6 forms tough, reliable welds with good bonding to the base metal, reducing the risk of cracking even on thick or stressed parts. -
Perfect for hardfacing or manufacturing technical parts:
This wire is commonly used for hardfacing bearings, bushings, slides, bushings, gear teeth or naval components, thanks to its combination of robustness and environmental resistance.
