A260Ni Aluminium Alloy
Precision Alloys is a specialized manufacturer and exporter of A260Ni Aluminum Alloy, a high-strength, nickel-modified aluminum alloy designed for critical aerospace, defense, and precision-engineered applications requiring excellent fatigue resistance, thermal performance, and dimensional stability.
We offer A260Ni alloy in rods, bars, forged blanks, machined parts, and custom-formed components, ideal for components exposed to high mechanical load and cyclic thermal stress.
What is A260Ni Aluminium Alloy?
A260Ni is a high-performance aluminum alloy that contains significant levels of copper and nickel, offering superior fatigue strength, wear resistance, and creep resistance at elevated temperatures. This alloy is ideal for structural parts in aerospace assemblies, precision-machined parts, and load-bearing forged components that demand long-term stability.
Its nickel enrichment improves its performance in high-load, high-frequency environments such as jet engines, automotive performance parts, and industrial dies.
