Chamber casting alloy

#1 Post by JD4570 »

Another item which may be of interest to people is chamber casting alloy.

We have the option of stocking a product that is the equivalent of the market leader, but approximately 35% cheaper.

Does this appeal?

It was the word "equivalent", it gave me vain hope that it might have been a better version.

I'll stick with impact casts and flowers of sulphur methods.
