Wieland-K12 and K14 are copper alloys used for applications needing good electrical conductivity. Weldability of the two alloys is slightly different. This datasheet provides information on composition, physical properties, and elasticity. It also includes information on corrosion resistance as well as forming and joining. Filing Code: CU-689. Producer or source: Wieland Metals Inc., Wieland-Werke AG.

K12 has a Ni-Mo-Cr alloy steel composition and possesses an appropriate combination of hardness and toughness mandatory for proper ballistics performance. K12 plate is normally supplied in the annealed condition so that it may be more easily cut and formed into the desired configuration. It may also be supplied as heat treated parts cut to the final configuration. This datasheet provides information on physical properties, hardness, tensile properties, and bend strength as well as fracture toughness. It also includes information on corrosion resistance as well as forming and joining. Filing Code: SA-560. Producer or source: Allegheny Ludlum.

ATI 500-MIL High Hard is a specialty steel of wrought Ni-Cr-Mo specialty steel for armor plate. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining. Filing Code: SA-606. Producer or source: ATI Defense.

HAYNES STELLITE No. 19 is a cobalt-base cutting tool alloy having high resistance to severe shock and excellent red-hardness. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness and creep. It also includes information on corrosion resistance as well as machining. Filing Code: Co-13. Producer or source: Haynes Stellite Company.
