Medical Grade Tantalum Wire
According to the purity, tantalum wire is divided into 3 categories:
(1)metallurgical tantalum wire, purity 99.0% Ta;
(2)high-purity tantalum wire, purity 99.0%~99.9%Ta;
(3) ultra-high purity tantalum wire, purity 99.9%~99.99% Ta.
Product Introduction
1. Product name: Medical grade tantalum wire
Tantalum wire is a filamentous tantalum material made of tantalum powder as raw material by rolling, drawing, and other plastic processing methods. Medical grade tantalum wire can be used in medicine as a material for orthopedic surgery, and it compensates for muscle tissue and can be used to suture nerves and tendons.

5. Production method
⑴ powder metallurgy
The process flow is: raw material (tantalum powder) → mixing → forming → vertical melting → rotary forging → intermediate annealing → drawing → finished annealing → quality inspection → packaging and storage.
⑵ smelting method
The technological process is: raw material (tantalum powder) → mixing → forming → pre-sintering → electron beam melting → precision forging → intermediate annealing → rotary forging → intermediate annealing → drawing → finished annealing → quality inspection → packaging and storage.
