Values for the CHILL condition
BrO10F1 tempers and conditions
BrO10F1 is supplied in 3 conditions, soft to hard. CHILL is the default FabDigit quotes; the values on this page are for it.
Compare all 3 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Sand cast | Pick for large, one-off or low-volume gear rims and housings where section thickness is high and strength demands moderate. | 130 | 250 | 5 | 85 HB | 10.5 % IACS |
CHILLDefault Chill / permanent-mould cast | The standard stocked condition for bushings, worm-wheel blanks and slide plates — finer structure and higher hardness than sand casting. | 155 | 290 | 6 | 100 HB | 10.8 % IACS |
Pressure die cast | Only for high-volume small thin-wall parts; fine grain gives good hardness but low ductility and possible gas porosity. | 170 | 300 | 3 | 110 HB | 11 % IACS |

What is BrO10F1?
BrO10F1 is a Russian-standard tin–phosphor bronze casting alloy corresponding to C90700, with a high tin content and a phosphorus addition that produces a hard, wear-resistant structure for gears and bearings. Typical properties are 155 MPa yield, 290 MPa tensile, 6 % elongation and 100 HB, supplied as sand, chill, centrifugal, continuous and die castings. It is specified in CIS-market equipment for compressively loaded parts; low ductility and poor fusion weldability mean it needs full support and machined-to-fit bores. PBC2 (C90700) is the direct Japanese-standard equivalent for the same duty. BrO10F1 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). BrO10F1 has a yield strength of 155 MPa (22.5 ksi) and a tensile strength of 290 MPa (42.1 ksi) — weaker than 65% of copper alloy grades. Elongation at break is 6% and the elastic modulus is 103 GPa (14.9 Msi).

Producing a kilogram of BrO10F1 takes about 58 MJ of energy and emits 4 kg of CO₂ — more than 61% of copper alloy grades. Typical recycled content is 55%.
Manufacturability7
BrO10F1's machinability is fair (42/100, better than 59% of copper alloy grades); weldability poor (25/100); formability not recommended (12/100).

Working with BrO10F1
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 — frequently asked
What is BrO10F1 used for?
BrO10F1 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?
BrO10F1 has a typical yield strength of 155 MPa (22.5 ksi) and a tensile strength of 290 MPa (42.1 ksi) — weaker than 65% of copper alloy grades. Strength varies by condition: see the 3 listed tempers.
Is BrO10F1 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 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?
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 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?
BrO10F1 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.
How much does BrO10F1 cost?
BrO10F1 is a high-cost copper alloy ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
