High Strengh Bras Material


(1) Features
In order to improve the base material (brass)’s general properties, such as the strength, toughness, abrasion resistance and friction coefficient, trace amounts of alloying elements were added and attributed a dramatic enhancements on above properties. For the alloy design and manufacturing purposes, various fine strengthening compounds were uniformly distributed in the matrix.

(2) Strength
Change of alloy design and manufacturing allowed improvements in various mechanical properties and lowered costs. It forms a robustness and stable matrix that has excellent abrasion resistance and hardness.

(3) Applied ITEM
