Secondary & Remelt Metal Trading

Secondary & Remelt Metal Trading

Secondary metal production refers to scrap which has been remelted to produce either a “secondary alloy” according to an agreed chemical and physical specification, or a “remelt” which would be produced to less strict analytical and physical specifications. The resulting secondary alloy or remelt may be cast out into a number of different shapes such as ingot, blocks, sow, billet and other transportable shapes.

Aluminium alloys are normally produced in the form of ingots by melting aluminium scrap and re-alloying it through the addition of certain other metals such as silicon. They are principally used in diecasting and foundry industries where the major consumption is within the automotive sector. The alloy would be melted and cast out by the foundry or diecaster into a new form creating products including cylinder heads, brake callipers and electrical items such as motor casings. Other alloys such as brass and copper are also produced from their own scraps by adding alloying elements for use in castings of, for example sanitary ware, valves and other electrical and mechanical parts.

Remelts which may be in any of the forms mentioned and would generally be used by producers of alloys or other downstream producers who would further alloy them with scrap or other elements to produce the required specification for the intended purpose; or consumed by refineries and smelters which would be seeking to isolate and upgrade the metals contained, by refining into more pure metals within the processes.
