Copper powder transforms sintered metal and metal injection molding (MIM) into powerful manufacturing tools. Its unique qualities create strong, precise parts for countless industries. In this article, we’ll look at the chemical composition, benefits, applications and standards from a variety of perspectives.
What Is Copper Powder?
It consists of fine copper particles, manufactured by atomization or electrolysis. These particles have excellent electrical conductivity and ductility. In sintered metals and MIM, it forms complex and durable parts. Its versatility makes it a necessity in today’s industry.

- MPIF Standard 35: Defines properties for top-quality copper powder.
Copper Powder in Sintered Metal and MIM
Sintered metals and MIM rely on copper powder for accuracy. During the sintering process, it is heated and melted into a solid shape. Metal Injection Molding mixes it with a binder, molds it, and then sinter it into complex parts. Both methods benefit from its strength and flexibility. This makes it the preferred choice for advanced production.
