Type‑based segmentation classifies Chrome Metal Lump into three core categories: Primary (raw) lump, Refined lump, and Alloyed lump. Primary lumps, sourced directly from mining operations, constitute the bulk of supply and are typically sold in low‑purity grades (≤ 90 % Cr) for bulk‑metal applications; they underpin the volume‑driven portion of the market. Refined lumps undergo metallurgical processing to achieve medium (90‑95 % Cr) and high‑purity (> 95 % Cr) grades, catering to sectors where precise alloy composition and surface finish are critical, such as aerospace and high‑performance automotive parts. Alloyed lumps integrate chrome with complementary elements (e.g., nickel, molybdenum) to produce tailored alloys for extreme‑stress environments, representing a higher‑margin, lower‑volume niche. The relative pricing hierarchy—primary < refined < alloyed—maps directly to market contribution, with primary lumps driving total tonnage, refined lumps adding value through premium pricing, and alloyed lumps enhancing overall market diversification.
