Product description: 

Lead zinc ore is gray and black powder,and is made by selected and crushed Sphalerite and galena sulfide ore.The mohs hardness is 3-5.5, the density is 4.5- 5.0 g/cm3.For the different melting point of sulfide,Lead zinc ore is used in friction material for adjusting high-temperature, improving friction coefficient and reducing the dosage of adhesive.It is specially suitable for rake pad Drum brake or clutch.The recommended regular consumption rate is about 2-8% according to the required function.

The character of Lead zinc ore:

Lead zinc ore  can be divided into two categories, sulfide ore and oxidized ore.The lead-zinc ore have the feature of anti-corrosion to acid and base.Lead zinc ore is of low hardness, low shear strength, low friction and low wear characteristics.So the Mechanical strength and friction performance of final products can achieve good effect.
