About Nonferrous-metals

Nonferrous metal refers to all the metal and alloys other than "iron" (steel material). Stainless steel, aluminum, copper, a copper alloy, etc. mainly correspond to this. We have various quotient materials in stock centering on nonferrous metal, and sell in the form of a plate, a bar and a pipe, etc., respectively.


Speaking of "copper", it generally refers to the C1100 (tough pitch copper). It excels in heat and electrical conductivity, malleability, ductility, drawability, weldability, corrosion resistance, and weather resistance, and is used for electric wire, cable and construction piping etc.

Copper alloy

A copper alloy is an alloy which mainly added tin, phosphorus, sulfur, nickel, etc. in copper for the purpose of the improvement of copper hardness, machinability, strength, corrosion resistance, etc. It is called the honor student of recycling for the reason that worth of the very thing itself is expensive and that reproduction use is comparatively easy.

Aluminum material

Aluminum is the aluminium alloy which added various elements to pure aluminum. It is lightweight, and is strong to corrosion, and what it is easy to process is the feature. It excels in thermal conductivity and electrical conductivity, it ranks next to iron, and has a large use.

Stainless steel material

Stainless steel (steel) is alloy steel with the iron in which chromium and nickel were included.It excels in rust prevention and corrosion resistance is the feature. The brevity code in JIS is set to SUS (Sas).
