Working with ADC6 HVDC-F
Is ADC6 easy to machine?
Machines easily but gummy — use sharp polished high-rake carbide, high speed, flood coolant or MQL to avoid built-up edge and smearing.
Can ADC6 be welded?
TIG/MIG weldable with 5356 filler on low-porosity (vacuum) castings; conventional HPDC parts blister and gas-porosity-crack, so prefer mechanical joining or friction-stir/laser on thin sections.
Can ADC6 be formed, bent or molded?
Die casting requires tight melt protection (cover flux/inert gas), controlled Fe/Mn to limit die soldering, fast fill and good venting; hot-tearing and short die life relative to ADC12.
What surface finishes work on ADC6?
Excellent candidate for clear and color sulfuric anodizing and chromate-free conversion coating; also takes powder coat and paint well after light shot blast.

ADC6 HVDC-F — frequently asked
What is ADC6 HVDC-F used for?
ADC6 HVDC-F is typically used for decorative fittings, corrosion-resistant housings and consumer hardware. In short: anodizable die-cast alloy; highest thermal conductivity ADC; easier casting than ADC5.
What is the yield strength of ADC6 HVDC-F?
ADC6 HVDC-F has a typical yield strength of 150 MPa (21.8 ksi) and a tensile strength of 280 MPa (40.6 ksi) — weaker than 65% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is ADC6 HVDC-F easy to machine?
Reasonably — machinability is rated good (67/100, better than 66% of aluminum grades). Machines easily but gummy — use sharp polished high-rake carbide, high speed, flood coolant or MQL to avoid built-up edge and smearing.
Can ADC6 HVDC-F be welded?
Yes — weldability is rated good (60/100). TIG/MIG weldable with 5356 filler on low-porosity (vacuum) castings; conventional HPDC parts blister and gas-porosity-crack, so prefer mechanical joining or friction-stir/laser on thin sections.
What surface finishes work on ADC6 HVDC-F?

Can ADC6 HVDC-F be formed, bent or molded?
Die casting requires tight melt protection (cover flux/inert gas), controlled Fe/Mn to limit die soldering, fast fill and good venting; hot-tearing and short die life relative to ADC12.
What is the maximum service temperature of ADC6 HVDC-F?
ADC6 HVDC-F 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 ADC6-F and ADC6-O?
F is the default condition — standard supply condition for ADC6 die castings; used directly after trimming and machining. O: pick when dimensional stability after machining matters more than strength; short low-temperature soak avoids blistering of the cast pores. Yield strength is 145 MPa in F versus 120 MPa in O.
