Rare MetalSource stocks over 8,000 items of ingot, billet, bar, and plate products. Our goal is not to stock every grade and size, but to stock a relatively narrow product mix and to constantly fine tune our inventory to meet the needs of our customers. Due to constant changes and our unique conversion options (forging, rolling, drawing, etc.), we do not publish a stock list. Instead, we provide a detail of our capabilities and a list of grades we stock.

The following products are listed by Grade, UNS, and available specifications:
