Working with ADC14-T5
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.
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-T5 — frequently asked
What is ADC14-T5 used for?
ADC14-T5 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-T5?
ADC14-T5 has a typical yield strength of 265 MPa (38.4 ksi) and a tensile strength of 295 MPa (42.8 ksi) — stronger than 69% of aluminum grades. Strength varies by condition: see the 4 listed tempers.
Is ADC14-T5 easy to machine?
Not especially — machinability is rated poor (32/100, worse than 89% 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-T5 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 surface finishes work on ADC14-T5?
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.
Can ADC14-T5 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.
What is the maximum service temperature of ADC14-T5?
ADC14-T5 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.
