Quick tip: the minus sign in mesh sizes (e.g. -200) means the powder passes through that sieve, so -200 mesh means every particle is smaller than 75 µm.

Frequently Asked Questions

BR-9010

Questions & Answers

What is BR-9010 pre-alloyed bronze powder used for?

BR-9010 is the workhorse bond matrix powder for diamond tool segments (saw blades, drill bits, grinding wheels) and is also used in powder metallurgy components, sintered structural parts and cold casting. The 90/10 Cu:Sn ratio balances hardness, toughness and sinterability.

Why choose pre-alloyed bronze over blended copper and tin?

Pre-alloyed powder carries the 90/10 composition inside every particle, so there is no segregation during handling and the alloy sinters with consistent phase distribution. Blended elemental powders offer ratio flexibility but demand tighter process control.

What mesh sizes and properties does BR-9010 offer?

BR-9010 comes in -100, -200 and -325 mesh with apparent density of 2.5 to 3.5 g/cc and hydrogen loss of 0.40% max. Finer grades give more uniform sintering and are typical for premium diamond tool segments.

When should I use BR-8515 instead?

Move to BR-8515 (85/15) when the application needs a harder, more wear-resistant matrix, for example cutting granite, reinforced concrete or other aggressive materials. Higher tin content raises matrix hardness at some cost in toughness.

Can I order small or sample quantities of BR-9010?

Sample quantities are available for formulation trials. UK stock grades typically dispatch within 48 hours in 1 kg, 5 kg or 25 kg packaging.

What documentation is supplied with BR-9010?

Every batch ships with ISO 9001 certified documentation, chemical analysis and batch traceability. Technical and Safety Data Sheets are available on request, with export handled for international customers.
