HK Bimetallic Barrel

• Producible barrel inner diameter (d): 16mm–400mm • Producible barrel outer diameter (D): ?500mm • Producible barrel length (L): ?10,000mm • Maximum centrifugal casting length (L): ?6,000mm • Inner surface roughness (Ra): 0.2 ? Ra ? 0.4 (Ra < 0.2 requires special customization) Performance Advantages: Through high-temperature centrifugal casting, the alloy powder is first melted and then solidified, forming a dense alloy layer on the inner wall of the barrel. This enhances its wear resistance and corrosion resistance.
