What is ADC10Z?
ADC10Z is ADC10 in the ADC10Z grade — jIS variant that tolerates up to ~3 % Zn from secondary scrap; used for non-critical cost-driven castings where corrosion exposure is low. ADC10Z has a yield strength of 165 MPa (23.9 ksi) and a tensile strength of 320 MPa (46.4 ksi) — weaker than 58% of aluminum grades. Elongation at break is 2.5% and the elastic modulus is 71 GPa (10.3 Msi). ADC10Z has a density of 2.78 g/cm³ (0.1 lb/in³), heavier than 74% of aluminum grades. It melts at 540°C (1,004 °F). F is the default condition FabDigit quotes; ADC10Z is available on request or by drawing note.

Working with ADC10Z
Is ADC10 easy to machine?
Machines freely with sharp PCD or polished-carbide tooling and high speeds; the eutectic Si is abrasive so PCD is preferred for volume, and subsurface porosity can appear when heavy stock is removed.
Can ADC10 be welded?
Not recommended for structural fusion welding — entrapped gas causes blowholes and Cu promotes hot cracking; use mechanical fastening, adhesive, or friction-stir/laser only on vacuum-cast parts.
Can ADC10 be formed, bent or molded?
Designed for cold-chamber high-pressure die casting: excellent fluidity for 1–2 mm walls, low hot-tear tendency, and stable die life at ~660–700 °C pour with proper Fe control.
What surface finishes work on ADC10?
Decorative anodizing is poor (dark, blotchy); specify chromate/trivalent conversion coating, powder coat, e-coat or paint, and hard anodize only where a functional grey wear layer is acceptable.

ADC10Z — frequently asked
What is ADC10Z used for?
ADC10Z is typically used for automotive brackets, electronics housings and appliance parts. In short: machinable general-purpose die casting; higher strength than ADC12; poor weldability and corrosion.
What is the yield strength of ADC10Z?
ADC10Z has a typical yield strength of 165 MPa (23.9 ksi) and a tensile strength of 320 MPa (46.4 ksi) — weaker than 58% of aluminum grades. Strength varies by condition: see the 4 listed tempers.
Is ADC10Z easy to machine?
Yes — machinability is rated very good (76/100, better than 87% of aluminum grades). Machines freely with sharp PCD or polished-carbide tooling and high speeds; the eutectic Si is abrasive so PCD is preferred for volume, and subsurface porosity can appear when heavy stock is removed.
Can ADC10Z be welded?
Not readily — weldability is rated poor (20/100). Not recommended for structural fusion welding — entrapped gas causes blowholes and Cu promotes hot cracking; use mechanical fastening, adhesive, or friction-stir/laser only on vacuum-cast parts.
What surface finishes work on ADC10Z?
Decorative anodizing is poor (dark, blotchy); specify chromate/trivalent conversion coating, powder coat, e-coat or paint, and hard anodize only where a functional grey wear layer is acceptable.

Designed for cold-chamber high-pressure die casting: excellent fluidity for 1–2 mm walls, low hot-tear tendency, and stable die life at ~660–700 °C pour with proper Fe control.
What is the maximum service temperature of ADC10Z?
ADC10Z is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ADC10-F and ADC10-O?
F is the default condition — standard supply condition for essentially all ADC10 die castings; no heat treatment, best dimensional stability. O: rarely ordered; a low-temperature anneal used to relieve casting stresses when tight post-machining stability is required, at the cost of strength. Yield strength is 160 MPa in F versus 120 MPa in O.
