What is 1050-F?
1050-F is 1050 in the F temper — cheapest hot-worked condition for plate/extrusion where mechanical properties are not guaranteed. 1050-F has a yield strength of 35 MPa (5.08 ksi) and a tensile strength of 80 MPa (11.6 ksi) — weaker than 96% of aluminum grades. Elongation at break is 25% and the elastic modulus is 69 GPa (10 Msi). 1050-F has a density of 2.71 g/cm³ (0.0977 lb/in³), lighter than 54% of aluminum grades. It melts at 646°C (1,195 °F). H14 is the default condition FabDigit quotes; F is available on request or by drawing note.

Working with 1050-F
Is 1050 easy to machine?
Soft and gummy — use polished high-rake carbide, high speed, low feed and flood coolant or lubricant; harder H16/H18 tempers cut and deburr much more cleanly.
Can 1050 be welded?
Excellent by GTAW/GMAW with 1100 or 1188 filler (4043 for restraint-free joints); the weld and HAZ revert to the O-temper strength.
Can 1050 be formed, bent or molded?
Outstanding cold formability — O/H22/H24 tempers deep-draw, spin and roll-form with very tight bend radii; expect strong springback-free but low-strength parts.
What surface finishes work on 1050?
Ideal for bright and clear anodizing, chemical brightening and mirror polishing; also takes conversion coating and painting well, but the soft surface scratches easily.

1050-F — frequently asked
What is 1050-F used for?
1050-F is typically used for chemical storage tanks, architectural panels and cladding, heat-exchanger plate, busbar and electrical conductors, spun lighting reflectors and food and chemical process vessels. In short: pure aluminum; excellent corrosion.
What is the yield strength of 1050-F?
1050-F has a typical yield strength of 35 MPa (5.08 ksi) and a tensile strength of 80 MPa (11.6 ksi) — weaker than 96% of aluminum grades. Strength varies by condition: see the 13 listed tempers.
Is 1050-F easy to machine?
Not especially — machinability is rated poor (25/100, worse than 96% of aluminum grades). Soft and gummy — use polished high-rake carbide, high speed, low feed and flood coolant or lubricant; harder H16/H18 tempers cut and deburr much more cleanly.
Can 1050-F be welded?
Yes — weldability is rated excellent (95/100). Excellent by GTAW/GMAW with 1100 or 1188 filler (4043 for restraint-free joints); the weld and HAZ revert to the O-temper strength.
What surface finishes work on 1050-F?
Ideal for bright and clear anodizing, chemical brightening and mirror polishing; also takes conversion coating and painting well, but the soft surface scratches easily.
Can 1050-F be formed, bent or molded?
Outstanding cold formability — O/H22/H24 tempers deep-draw, spin and roll-form with very tight bend radii; expect strong springback-free but low-strength parts.
What is the maximum service temperature of 1050-F?
1050-F 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 1050-H14 and 1050-H111?
H14 is the default condition — the general-purpose stocked temper: usable strength and stiffness with still-good bending for sheet, coil and tread plate. H111: nearly soft sheet/plate that has picked up slight work during flattening or straightening; formability close to O. Yield strength is 90 MPa in H14 versus 25 MPa in H111.
