FAQ
Q: What automotive-grade aluminum alloys do you use for V8 engine
blocks?
A: We work with various automotive-grade aluminum alloys: A356-T6
(standard automotive, good castability, widely used), A357-T6
(higher strength, premium automotive), 6061-T6 (good machinability,
versatile), 7075-T6 (high strength, racing applications), and
custom aluminum alloys. All materials come with full material
traceability certification. Material selection depends on your
performance requirements, weight targets, strength specifications,
and heat treatment requirements.
Q: What cylinder bore tolerances can you achieve on V8 engine
blocks?
A: We achieve cylinder bore tolerances within +/-0.01mm, bore
cylindricity within 0.005mm, bore surface roughness within Ra
