Overview

Product details: Hard alloy rod products mainly include fine-grained and ultrafine grained hard alloy products

Product Details

Hard alloy rod products are mainly fine-grained and ultrafine grained hard alloy products, with a grain size between 0.5-0.8 μ m and high hardness, strength, and wear resistance. Hard alloy rod products are mainly used in the manufacturing of hard alloy integral cutting tools, and their end products mainly include drill bits, end mills, reamers, etc. They are widely used in metal processing, automotive manufacturing, aerospace, and digital 3C fields
