Broder Metals Group supply alloy 625 in a range of sizes from 6mm dia to 101.6mm dia, however we can obtain larger sizes on request.

We stock Alloy 625 in the annealed condition to provide good strength and hardness. Typical applications are where contact with sea water and other harsh chemical environments and mechanical stresses apply.

Although most core stock is in round bar we can also supply rings and bored bar – please contact us with your requirements.

Material is made with a fine grained melting method practice.
