Description
🟡 Precision H62 Brass Foil – Stable CuZn38 Alloy, ASTM B36
🔹 Overview
H62 brass foil is a high-performance, precision-rolled copper-zinc alloy material known for its exceptional strength, corrosion resistance, and excellent formability. With a nominal copper content of 62% and zinc balance, H62 belongs to the CuZn38 family and is widely used in electronic, automotive, decorative, and industrial applications. Manufactured in compliance with ASTM B36 standards, this foil is supplied in half-hard temper for optimal mechanical stability and workability.
Thanks to its excellent surface quality and tight thickness tolerance, H62 brass foil has become a preferred choice for designers and engineers working in advanced assembly processes. Its high electrical conductivity and stable metallurgical properties ensure consistent performance in critical parts. Moreover, its adaptability to laser cutting, chemical etching, CNC punching, and fine embossing makes it a top-tier candidate in both high-volume and precision-based manufacturing environments.
In recent years, the demand for H62 brass foil has surged in green energy systems and electric vehicles (EVs), where copper-based alloys play a vital role in connector and battery component reliability. Its combination of mechanical strength and corrosion resistance helps improve long-term stability, especially in outdoor or humid environments. The recyclable nature of brass also aligns with global sustainability goals, making H62 a smart material choice from both economic and ecological perspectives.
