About zinc, nickel & alloys scrap
Zinc turns up mainly as die-castings — carburettor bodies, hardware, toy and fitting castings — and as by-products of galvanising: dross, ash and skimmings from hot-dip plants. Galvanising by-products are bought on assay because the recoverable zinc percentage varies widely between plants.
Nickel-bearing scrap includes nickel alloy offcuts, plating anodes, monel and inconel from process industries. These are specialty materials and are almost never worth selling in a mixed stainless load; they are analysed and quoted individually.
If you are not sure what an alloy is, do not guess and do not sell it as mixed metal. Send a photo and we will identify it, then quote against the actual composition.
