Copper Strips: Types, Uses, and Buying Guide for 2025
Copper strips are essential in industries like electronics, construction, and automotive due to their excellent conductivity and durability. This guide covers their types, applications, and how to source them reliably.
How to Find Reliable Copper Strips from China in 2025
China remains a top supplier of copper strips, but buyers must verify certifications like ISO 9001 and RoHS. Platforms like Alibaba list vetted manufacturers, but always request samples and check customer reviews.
What Buyers Should Know Before Buying Copper Strips from China
Key factors include material purity (99.9% electrolytic copper is ideal), thickness tolerance (±0.02mm), and packaging standards. Negotiate MOQs and shipping terms upfront to avoid surprises.
Types of Copper Strips
1. Pure Copper Strips: High conductivity for electrical applications.
2. Oxygen-Free Copper (OFC): Minimal impurities, used in premium audio equipment.
3. Alloy Strips: Mixed with tin or zinc for enhanced strength.
Functions and Features of Copper Strips
These strips offer:
- Thermal conductivity (385 W/m·K)
- Corrosion resistance (ideal for marine environments)
- Flexibility (can be bent without cracking)
Scenarios of Copper Strips
Common uses include:
- Circuit boards (due to solderability)
- Roofing (weather-resistant properties)
- Transformers (efficient energy transfer)
How to Choose Copper Strips
Match the strip to your project:
1. Electrical projects: Prioritize conductivity (≥100% IACS).
2. Outdoor use: Choose tinned or nickel-plated variants.
3. Budget constraints: Alloy strips offer cost savings.
