Product Tags

The bimetallic barrel is a wear-resistant, corrosion-resistant, high-humidity alloy cast on the inner wall of the barrel with a layer of 2-3mm. Its effective service life is greatly improved compared to ordinary nitride barrels. , PPO special types of plastics, etc., the superiority of bimetal is particularly obvious. We can use different alloys and welding methods for screws with different functions.
