Premium Decorative Brass & Copper Sheets 0.15mm-2.2mm 1/4H Temper For Construction, Electronics

Q1: What is the advantage of a 1/4H temper?
A: A 1/4 Hard (1/4H) temper provides an optimal balance between ductility and strength. It is softer than full-hard tempers, making it easier to form and bend, while still being stronger and more spring-like than annealed (soft) copper, holding its shape better after fabrication.

Q2: Are these copper sheets suitable for outdoor architectural use?
A: Yes, copper and its alloys like brass are excellent for outdoor applications. They develop a protective patina over time, which enhances their weather resistance and provides a unique, evolving aesthetic. The specific alloy grade can be selected for optimal performance in your environment.

Q3: Can you provide custom-cut sizes and shapes?
A: Absolutely. We offer comprehensive processing services including decoiling, cutting, punching, and bending. You can order the sheets in the exact dimensions and shapes required for your project, minimizing waste and streamlining your production process.

Q4: What is the difference between the C1020 and C1100 grades?
A: Both are high-purity copper grades. C1100 (also known as Electrolytic Tough Pitch Copper) is the most common commercial copper, with excellent conductivity. C1020 is Oxygen-Free Copper, which is better suited for high-temperature applications in reducing atmospheres where hydrogen embrittlement is a concern.

Q5: Why is high elongation (≥30%) important?
A: A high elongation value indicates the material's high ductility. This means the sheet can be bent, stretched, and formed significantly without cracking or breaking, which is essential for complex fabrication processes and ensures durability in the final product.
