Diamond Chain Company's proprietary metallurgical process is at the very core of the Diamond Diference. It begins with our careful selection of raw materials. Diamond Chain Company specifies the metal grade, mechanical properties, and carbon and alloy content that assure the consistent high performance of every Diamond chain. We also engineer our material chemistry to minimize impurities, which maximizes tensile and fatigue strength. Because of our proprietary material and metallurgical specifications, Diamond chains are able to hold much tighter tolerances during fabrication and product assembly than competing chains. This assures you of reliable high performance that minimizes downtime and keeps your operation running smoothly.
