What Is A380 Aluminum Casting Alloy?<\/h2>\n

Linsy A380 is the most widely specified aluminum-silicon-copper die casting alloy. It combines excellent castability, good mechanical properties, and economic pricing, with resistance to stress-corrosion cracking and reliable dimensional stability in complex, thin-walled parts. A380 is normally used in the as-cast (F) condition without further heat treatment, though T5 is sometimes applied for added stability.<\/p>\n

Temper<\/th>\nWhen to Use<\/th>\n<\/tr>\n<\/thead>\n
F (as-cast)<\/td>\nAs-cast, no heat treatment. Best economy and dimensional stability for die and sand castings.<\/td>\n<\/tr>\n

Key Characteristics of A380 Aluminum<\/h2>\n

Excellent Castability<\/h3>\n

High silicon and copper give A380 superior fluidity and filling of thin, complex dies at high production rates.<\/p>\n

Good Strength & Stiffness<\/h3>\n

Among the strongest common die-cast alloys, A380 suits load-bearing brackets and housings.<\/p>\n

Dimensional Stability<\/h3>\n

Low tendency to warp or shrink supports tight-tolerance high-volume production.<\/p>\n
