What is Coiled H65 Copper Wire?
Our Coiled H65 Copper Wire (Yellow Brass Wire) is a cornerstone material for modern manufacturing. Often referred to as 65/35 brass due to its copper and zinc ratio, H65 offers a unique combination of high elongation and respectable tensile strength.
The "Coiled" format is specifically designed for industrial-scale operations. Unlike small spools, our large-capacity coils are engineered for seamless integration with heavy-duty machinery used in fastener production, mesh weaving, and electrical component forming. Each coil undergoes strict tension and alignment checks to guarantee a consistent payoff speed, preventing wire breakage and optimizing your factory's output efficiency.
H65 solid copper wire has the following advantages:
1. good electrical conductivity: copper is a metal material with high electrical conductivity, which can ensure good electrical conductivity.
2. Strong corrosion resistance: zinc plays a protective role for copper in the alloy, which can effectively prevent copper from being oxidized, thus prolonging the service life of brass wire.
3. Convenient processing: H65 brass wire has good ductility and weldability, which is convenient for processing and connection.
4. Wide range of applications: H65 brass wire is widely used in electronics, electrical appliances, communications, automobiles, machinery and other fields.

When choosing H65 metal copper wire, you need to consider the following aspects:
1. Appearance: high-quality H65 brass wire has a smooth surface, without oil, oxidation, discoloration and other phenomena.
2. Material: choose H65 brass wire with appropriate ratio of copper-zinc alloy, too high copper content will make the material hard and unfavorable for processing, while too low copper content will make the material too soft and insufficient strength and hardness.
3. Specification: Choose the appropriate wire diameter and specification according to the actual need.
4. Performance: High-quality H65 brass wire has good electrical conductivity and corrosion resistance, and can meet the requirements for use in various harsh environments.
