Do you work in other metals besides stainless steel and aluminium?

We work only with stainless steel and aluminium. The reason for this is simple: if you work with both stainless and normal metals, the stainless steel does not remain clean. If you use a grinding disc, for argument’s sake, on both mild steel and stainless steel, the stainless steel becomes contaminated. This means that your product won’t have the properties you originally required.
