What is BrO10F1 SAND?
BrO10F1 SAND is BrO10F1 in the SAND condition — pick for large, one-off or low-volume gear rims and housings where section thickness is high and strength demands moderate. BrO10F1 SAND has a yield strength of 130 MPa (18.9 ksi) and a tensile strength of 250 MPa (36.3 ksi) — weaker than 77% of copper alloy grades. Elongation at break is 5% and the elastic modulus is 100 GPa (14.5 Msi). BrO10F1 SAND has a density of 8.76 g/cm³ (0.316 lb/in³), heavier than 51% of copper alloy grades. It melts at 830°C (1,526 °F). CHILL is the default condition FabDigit quotes; SAND is available on request or by drawing note.

Working with BrO10F1 SAND
Is BrO10F1 easy to machine?
Unleaded and gummy — use sharp positive-rake carbide, high speed with modest feed and coolant; chipbreakers needed, rating ≈20 % of AISI 1212.
Can BrO10F1 be welded?
Poor fusion weldability (hot-shortness and P loss); repair by TIG/oxy-fuel with matching phosphor-bronze rod, preheat 150–250 °C, or braze instead.
Can BrO10F1 be formed, bent or molded?
Casting alloy only — wide freezing range means generous risers, chills and directional solidification to avoid interdendritic shrinkage; centrifugal or continuous casting gives the soundest metal.
What surface finishes work on BrO10F1?
Polishes to a bright golden finish; accepts tin, nickel or chrome plating with proper cleaning; running surfaces are usually finish-bored/honed and left bare for oil retention.

BrO10F1 SAND — frequently asked
What is BrO10F1 SAND used for?
BrO10F1 SAND is typically used for worm gears, bushings and pump parts. In short: CIS-standard gear bronze; hard, low-ductility wear bronze; continuous-cast bushing stock.
What is the yield strength of BrO10F1 SAND?
BrO10F1 SAND has a typical yield strength of 130 MPa (18.9 ksi) and a tensile strength of 250 MPa (36.3 ksi) — weaker than 77% of copper alloy grades. Strength varies by condition: see the 3 listed tempers.
Is BrO10F1 SAND easy to machine?
Not especially — machinability is rated fair (42/100, better than 59% of copper alloy grades). Unleaded and gummy — use sharp positive-rake carbide, high speed with modest feed and coolant; chipbreakers needed, rating ≈20 % of AISI 1212.
Can BrO10F1 SAND be welded?
Not readily — weldability is rated poor (25/100). Poor fusion weldability (hot-shortness and P loss); repair by TIG/oxy-fuel with matching phosphor-bronze rod, preheat 150–250 °C, or braze instead.
What surface finishes work on BrO10F1 SAND?
Polishes to a bright golden finish; accepts tin, nickel or chrome plating with proper cleaning; running surfaces are usually finish-bored/honed and left bare for oil retention.
Can BrO10F1 SAND be formed, bent or molded?
Casting alloy only — wide freezing range means generous risers, chills and directional solidification to avoid interdendritic shrinkage; centrifugal or continuous casting gives the soundest metal.
What is the maximum service temperature of BrO10F1 SAND?
BrO10F1 SAND is rated for continuous use to about 250°C (482 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between BrO10F1 CHILL and BrO10F1 SAND?
CHILL is the default condition — the standard stocked condition for bushings, worm-wheel blanks and slide plates — finer structure and higher hardness than sand casting. SAND: pick for large, one-off or low-volume gear rims and housings where section thickness is high and strength demands moderate. Yield strength is 155 MPa in CHILL versus 130 MPa in SAND.
