IS 7138:1994 is the Indian Standard (BIS) for aluminium alloy die castings. IS 7138 covers aluminium alloy die castings — high-volume production castings made by injecting molten aluminium into steel dies under pressure. Used for automotive, electrical, and hardware components.

Specification for aluminium alloy die castings covering grades, chemical composition, mechanical properties, and quality requirements.

Overview

2Key values 2Tables 1FAQs

Practical Notes

! ADC12 (Al-Si-Cu alloy) is the most common die casting alloy in India — 80%+ of all die castings.

! Die castings have porosity — not suitable for pressure-tight applications without impregnation.

! Surface finish from die casting is excellent (Ra 1.6-3.2 µm) — often used without machining.
