The performance of concrete diamond drill bits heavily relies on matrix raw materials. As a core raw material, qualified pre-alloy powder directly decides diamond retention capacity, wear resistance and overall service life of drilling segments. Ordinary mixed elemental metal powder easily causes component segregation and high sintering temperature, which damages diamond crystals during production. Against this backdrop, fine copper-tin alloy powder becomes a preferred option for manufacturing diamond drill bits.
Sagwell is a professional factory focusing on superhard tool metal powder. Our DY series copper-tin pre-alloy powder is specially developed as alloy powder for diamond drill bits, tailored to complex concrete drilling conditions. Adopting integrated atomization technology, the powder delivers even element distribution without agglomeration. It supports a sintering temperature range of 550–750°C, effectively avoiding diamond graphitization.
Multiple graded tin content formulas are available to match ordinary concrete, reinforced concrete and heavy-duty drilling scenarios. Compatible with hot pressing and pressureless sintering processes, the powder allows flexible proportion adjustment.
Unlike general powder distributors, Sagwell offers systematic technical support including formula optimization and sintering parameter debugging. Strict batch-by-batch inspection guarantees stable powder quality, helping drill bit manufacturers reduce reject rates.
