What is ADC14?
ADC14 is a hypereutectic Al-Si die casting alloy from the JIS ADC family (close to A390.0) in which primary silicon particles and copper give hardness and wear resistance instead of ductility. Engineers specify it for as-cast compressor and pump parts running against sliding surfaces, with 240 MPa yield, 280 MPa tensile, 120 HB and only 1% elongation. Service is limited to about 200 °C, thermal conductivity is 134 W/m·K and electrical conductivity 27% IACS. The abrasive primary Si makes machining slow (machinability score 30) and structural welding is not recommended; ADC12 is the alternative when ductility and castability matter more than wear. ADC14 has a density of 2.73 g/cm³ (0.0986 lb/in³), heavier than 61% of aluminum grades. It melts at 507°C (945 °F). ADC14 has a yield strength of 240 MPa (34.8 ksi) and a tensile strength of 280 MPa (40.6 ksi) — stronger than 63% of aluminum grades. Elongation at break is 1% and the elastic modulus is 81 GPa (11.7 Msi).

Working with ADC14
Is ADC14 easy to machine?
Highly abrasive primary silicon: use PCD or diamond-coated tools, high surface speed, low feed and copious coolant; carbide life is very short.
Can ADC14 be welded?
Not recommended for structural joints — Cu content and gas porosity cause hot cracking; repair only with 4047/4145 filler on clean, low-porosity sections.
Can ADC14 be formed, bent or molded?
Cold-chamber die casting at 680–720 °C with controlled melt superheat and grain-refined/P-modified Si; no cold forming possible, and abrasive wear of dies and shot sleeves must be budgeted.
ADC14 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on ADC14?
Chromate-free conversion coating, painting or powder coating is the usual route; anodizing yields a dark grey uneven film, and polishing is limited by exposed Si particles.

ADC14 — frequently asked
What is ADC14 used for?
ADC14 is typically used for compressor parts, wear plates and pump components. In short: wear-resistant hypereutectic Al-Si; hardest ADC casting alloy; low ductility, abrasive machining.
What is the yield strength of ADC14?
ADC14 has a typical yield strength of 240 MPa (34.8 ksi) and a tensile strength of 280 MPa (40.6 ksi) — stronger than 63% of aluminum grades. Strength varies by condition: see the 4 listed tempers.
Is ADC14 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 92% of aluminum grades). Highly abrasive primary silicon: use PCD or diamond-coated tools, high surface speed, low feed and copious coolant; carbide life is very short.
Can ADC14 be welded?
Not readily — weldability is rated poor (20/100). Not recommended for structural joints — Cu content and gas porosity cause hot cracking; repair only with 4047/4145 filler on clean, low-porosity sections.

What is the maximum service temperature of ADC14?
ADC14 is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ADC14-F and ADC14-T6?
F is the default condition — standard commercial condition for ADC14 die castings where wear resistance and dimensional stability matter more than strength. T6: highest strength and hardness for machined wear surfaces; only usable on low-porosity (vacuum or squeeze) castings because solutionising can blister gas-porous die castings. Yield strength is 240 MPa in F versus 305 MPa in T6.
