Aluminum Alloy鋁合金

Aluminum alloys resist corrosion, conduct electricity and heat well, are light, are non-toxic, and are easy to work. They are widely used in home appliances, communication equipment, mobile phones, computer peripherals, heat sinks, tableware, food packaging, building materials, lighting, automobiles, aerospace equipment, and more.

SummarySursun Metals supplies a range of aluminum alloys. The 1000 series is pure aluminum. For slightly higher strength choose the 3000 series, for medium strength choose 5052, and for structural use choose 6061.

How to Read Temper Symbols

The temper shows what working or heat treatment the aluminum has had. It affects softness, hardness, and strength.

Temper symbols in brief
Symbol	Meaning
O	Soft (annealed) condition
H1x	Strain-hardened only, with no heat treatment
H2x	Strain-hardened, then partially annealed
H3x	Strain-hardened, then stabilized
Hx2, x4, x6, x8, x9	Degree of hardening (about 1/4, 1/2, 3/4, full hard, extra hard). A larger number means harder.
T6	Solution heat-treated, then artificially aged without cold working
