Copper Alloy Sheet ASTM B370 - 60-80 MPa Tensile Strength Architectural Cladding
ASTM B370 Copper Alloy Sheets are designed for modern architectural projects requiring aesthetic appeal, durability, and sustainability. With a tensile strength of 60–80 MPa and compliance with ASTM B370, EN 1172, and LEED v4.1 standards, these sheets are ideal for façades, roofing, and decorative elements. Available in thicknesses from 0.5mm to 6mm, they combine natural corrosion resistance with design flexibility for iconic buildings.
Key Advantages:
- Architectural Elegance: Develops a natural patina over time or retains polished/brushed finishes.
- Lightweight & Durable: 60–80 MPa tensile strength for structural cladding without heavy supports.
- Corrosion Resistance: Resists urban pollution, salt spray, and humidity (ISO 9227 tested).
- Sustainability: 100% recyclable, with LEED and Cradle-to-Cradle (C2C) certifications.
- Customization: Pre-patinated finishes, perforated patterns, and custom dimensions (up to 3000x1500mm).
- Global Compliance: ASTM B370, EN 1172, and ISO 14001 (eco-friendly production).
