Which Minerals Include Phosphate?

 · Variscite is a hydrous aluminum phosphate, Al(H 2 O) 2 (PO 4), with a Mohs hardness of around 4. It forms as a secondary mineral near the surface in places where clay minerals and phosphate minerals occur together. As these minerals break down, variscite forms in massive veins or crusts. Crystals are small and very rare.

Aluminum Bronze Hanger Bearings for Searles Valley Minerals

Aluminum bronze C95400 was chosen because it provided superior strength and wear resistance when compared to bronze. Searles Valley Minerals had a very special bearing design that required special programming and CNC machining. KWS sent 3D models of the bearings to Searles Valley Minerals to confirm the dimensions of the non-CEMA sizes.

What is Bauxite?

Bauxite is a high-aluminum-content rock. That is the main ore that aluminium is mined from. One of the most common elements on earth is bauxite. It contains almost 25 percent-30% alumina. In the belt around the equator, bauxite is commonly found. The primary aluminium bearing ore with an aluminium content of more than 35 to 40 percent is bauxite.

Bearing Materials

Tin aluminium bearings were developed to provide bearings that carry high loads. As a bearing material, unalloyed aluminium has a tendency to seize to a steel mating surface. It was found that 20% of tin added to the aluminium improved seizure resistance and that cold working and annealing helped to prevent brittleness.
