CRCA: Cold rolled close annealed,the sheet is rolled below the recrystalization temaparature of the steel,this type of sheets will have close tolerance,good finish and better mechanical strength ... Al 3003 = Al 1100 + 1.25% Mn Tensile Strength = 110 Mpa General Purpose Alloy 5xxx Alloys: Al + Up To 5% Mg A15052 = Al + 25%Mg + 0.2% Cr Tensile Strength = 193 Mpa Used In Bus, Truck And Marine Sheet Metals.

Through-Hardening Low Alloy Steel Bar 4340 Colour code: Jade (Band) - Marigold Introduction Atlas 4340 is a nominally 1.8 percent Nickel Chromium Molybdenum low alloy steel of high hardenability, with high strength and toughness in relatively large sections achieved with a "quench-and-temper" heat treatment. Alloy 600 is a nonmagnetic, nickel-based high temperature alloy possessing an excellent combination of high strength, hot and cold workability, and resistance to ordinary form of corrosion. This alloy also displays good heat resistance and freedom from aging or stress corrosion throughout the annealed to heavily cold worked condition range.
