Description

Description

Overview:

The Monel 502 is a superalloy that possesses the capability to function well at significantly high temperatures. Not just that, it has been designed to handle the severe form of mechanical stress. The alloy comes with a goof creep & oxidation resistance.

The nickel-copper composition of the alloy allows it to be molded into varying shapes. They can easily be used for solid-solution hardening, precipitation hardening, as well as work hardening to increase the overall strength.

Monel 405: A free-machining alloy of the Monel 400, this metal is used primarily for the automatic screw stocks for the machine.

Frequently Asked Questions:

What is the difference between Monel and cupronickel?

The prime difference between cupronickel and Monel is the fact that the former houses 60 percent or more copper, while the latter is composed primarily of nickel.
