HVAC & Refrigeration Metals
Ductwork aluminum, refrigerant copper & structural framing. Aluminum for ductwork and framing, copper for refrigerant lines and heat exchangers.
Recommended Alloys
Aluminum sheet for duct fabrication, copper tube for refrigerant lines, and structural extrusions for equipment framing.
3003-H14 Aluminum
Ductwork & enclosures
The HVAC industry standard for duct fabrication. Most formable common aluminum — excellent for brake bending, seaming, and riveting. Low cost and corrosion resistant, making it the default sheet metal for residential and commercial ductwork.
C122 Copper
Refrigerant lines & heat exchangers
DHP copper is the standard for brazed refrigerant lines and heat exchanger tubes. The phosphorus content enables clean silver brazing without flux contamination — critical for sealed refrigerant circuits in air conditioning and refrigeration systems.
6063-T52 Aluminum
Conduit & structural framing
6063 is used for electrical conduit, equipment mounting frames, and duct support structures in commercial HVAC installations. Lightweight, corrosion resistant, and available in a wide range of extruded structural shapes.
New to HVAC fabrication?
Start with 3003-H14 for ductwork — it’s the industry standard and the most cost-effective option. Add C122 copper for refrigerant lines and 6063 for structural framing.
