Wieland Chase’s C87500 Silicon Brass is a lead-free, high-performance granular alloy designed for strength, corrosion resistance, and casting precision in small-batch applications. Made from ≥79% copper, 12–16% zinc, and 3–5% silicon, C87500 delivers excellent durability and long-term performance in challenging environments such as marine hardware, plumbing systems, and custom industrial parts.
Its granular form is perfect for users who want to melt only what they need—no cutting, no excess, and less waste. This makes it ideal for short-run jobs, prototype work, or low-volume custom casting. With a melting point of 1680°F, C87500 offers smooth mold flow, low dross, and compatibility with soldering, brazing, and gas-shielded arc welding. Backed by Wieland Chase’s industry-leading service, C87500 provides small users with professional-grade results and consistent quality every time. Certified Chemistry is supplied with every batch of material.

Elevate your casting operations with Wieland Chase’s C87500 silicon brass granular ingot, a lead-free alloy designed for superior performance, cost-efficiency, and compliance. Its innovative granular form enhances melting efficiency, making it an ideal choice for industrial, marine, and architectural applications.
Superior Quality and Performance
C87500 silicon brass, with 79% minimum copper, 12-16% zinc, and 3-5% silicon, meets ASTM B30 and B584 standards, ensuring consistent quality. Boasting 67 ksi tensile strength, 30 ksi yield strength, and 21% elongation, it offers durability and excellent castability. With a 50% machinability rating and hardness of 115-134 HB, C87500 excels in crafting bearings, gears, valve bodies, and decorative hardware. Its corrosion resistance, especially to saltwater, ensures reliable performance in marine and plumbing applications.
Efficiency Through Granular Innovation
The granular ingot format increases surface area, accelerating melting by up to 30% and reducing BTU consumption by up to 10% when compared to traditional brick ingots. This lowers energy costs, CO₂ emissions, and dross, while enabling automation-friendly handling for safer, streamlined production. These benefits make C87500 a standout for efficient foundry operations.
