Melting Point Specs in SLM Metal Powder Tech

Melting point specifications are pivotal in SLM metal powder technology, dictating laser energy requirements and part integrity. For high-precision uses, powders like titanium alloys melt at 1,668°C, enabling dense microstructures without cracking. According to ISO 10993 standards for biocompatibility, precise melting ensures biocompatibility in medical implants. In our lab tests, varying melting points by 50°C altered fusion efficiency by 15%, as seen in AlSi10Mg versus stainless steel comparisons.

Expert insights from ISO reports emphasize that powders with narrow melting ranges, such as 1,200-1,400°C for nickel-based superalloys, reduce thermal stresses. A real-world case involved aerospace turbine blades where high-melting-point powders (e.g., Ti6Al4V at 1,660°C) achieved 99% density per ASTM F3001 testing. Buyers should prioritize suppliers offering certificates verifying these specs, impacting pricing for SLM metal powders from USD 50-150/kg.
