Working with 5050-H112
Is 5050 easy to machine?
Gummy like all 5000 series — use sharp polished high-rake carbide, high surface speed and flood/mist lubricant to avoid built-up edge; H34/H38 tempers chip more cleanly than O.
Can 5050 be welded?
Readily GTAW/GMAW welded with 5356 or 5183 filler (4043 acceptable for lower strength); joints return to near-O strength in the HAZ, no post-weld heat treatment possible.
Can 5050 be formed, bent or molded?
Excellent cold formability in O/H32; allow larger bend radii and expect springback in H36/H38, and anneal at ~345 °C if severe redraws are needed.
What surface finishes work on 5050?
Anodizes to a clear, bright decorative film and takes dye well; also paints and chemically brightens easily, but avoid heavy Mg-rich surface smut by proper deox before anodizing.

5050-H112 — frequently asked
What is 5050-H112 used for?
5050-H112 is typically used for refrigerator and appliance tubing, architectural sheet and trim, anodized decorative trim, drawn tube for fluid lines, roll-formed coil stock and formed appliance panels. In short: tubing and sheet for general use.
What is the yield strength of 5050-H112?
5050-H112 has a typical yield strength of 70 MPa (10.2 ksi) and a tensile strength of 150 MPa (21.8 ksi) — weaker than 92% of aluminum grades. Strength varies by condition: see the 15 listed tempers.
Is 5050-H112 easy to machine?
Not especially — machinability is rated poor (33/100, worse than 87% of aluminum grades). Gummy like all 5000 series — use sharp polished high-rake carbide, high surface speed and flood/mist lubricant to avoid built-up edge; H34/H38 tempers chip more cleanly than O.
Can 5050-H112 be welded?
Yes — weldability is rated excellent (88/100). Readily GTAW/GMAW welded with 5356 or 5183 filler (4043 acceptable for lower strength); joints return to near-O strength in the HAZ, no post-weld heat treatment possible.
What surface finishes work on 5050-H112?
Anodizes to a clear, bright decorative film and takes dye well; also paints and chemically brightens easily, but avoid heavy Mg-rich surface smut by proper deox before anodizing.
Can 5050-H112 be formed, bent or molded?
Excellent cold formability in O/H32; allow larger bend radii and expect springback in H36/H38, and anneal at ~345 °C if severe redraws are needed.
What is the maximum service temperature of 5050-H112?
5050-H112 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.
Can FabDigit make parts in 5050-H112?
Yes — 5050-H112 is available for CNC machining and sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
