Alloy numbering systems vary greatly from one alloy group to the next. To help alleviate this problem the Unified Numbering System (UNS) for metals and alloys was developed. An outline of the organization of UNS designations is listed below:

	UNS Series	Metal
	A00001 to A99999	Aluminum and aluminum alloys
	C00001 to C99999	Copper and copper alloys
	D00001 to D99999	Specified mechanical property steels
	E00001 to E99999	Rare earth and rare earthlike metals and alloys
	F00001 to F99999	Cast irons
	G00001 to G99999	AISI and SAE carbon and alloy steels (except tool steels)
	H00001 to H99999	AISI and SAE H-steels
	J00001 to J99999	Cast steels (except tool steels)
	K00001 to K99999	Miscellaneous steels and ferrous alloys
	L00001 to L99999	Low-melting metals and alloys
	M00001 to M99999	Miscellaneous nonferrous metals and alloys
	N00001 to N99999	Nickel and nickel alloys
	P00001 to P99999	Precious metals and alloys
	R00001 to R99999	Reactive and refractory metals and alloys
	S00001 to S99999	Heat and corrosion resistant (stainless) steels
	T00001 to T99999	Tool steels, wrought and cast
	W00001 to W99999	Welding filler metals
	Z00001 to Z99999	Zinc and zinc alloys
