H85 Thin Copper Strips
Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of h85 thin copper strips in China, also supports customized service. Welcome to buy discount h85 thin copper strips for sale here from our factory. Quality products and reasonable price are available.
H85 copper strip is composed of copper as the basic element, with appropriate amounts of zinc, nickel, manganese and other alloying elements. This alloy has high strength and hardness, while maintaining good plasticity and toughness. In addition, H85 copper alloy has good electrical conductivity and corrosion resistance, as well as high fatigue strength and wear resistance. These excellent properties make H85 copper alloys promising for a wide range of applications in many fields.

Key Features
Premium "Red Gold" Color: Its warm, reddish-gold hue closely resembles 18K gold, making it ideal for costume jewelry, badges, and luxury hardware.
Ultra-Thin Precision: Advanced rolling technology allows us to produce foils as thin as 0.05mm with strict thickness tolerances (±0.003mm).
Superior Corrosion Resistance: The higher copper content provides excellent resistance to atmospheric corrosion, water, and stress cracking (better than H62/H65).
Excellent Cold Workability: Highly ductile and malleable. Perfect for deep drawing, spinning, embossing, and complex forming without cracking.

Application areas
H85 thin copper strip has high strength and hardness, it is widely used in the manufacture of a variety of high-strength, high wear-resistant parts, such as gears, bearings, bushings and so on. Meanwhile, due to its good electrical conductivity and corrosion resistance, H85 copper alloy strip is also widely used as conductive and corrosion-resistant parts in electronic and electrical industries. In addition, H85 copper foil rolls have a wide range of applications in chemical, construction, transportation and other fields.
Packaging of H85 thin copper alloy strips
Core Protection: Strips are wound on fiber or steel cores (ID: 150mm/300mm/500mm) to prevent collapsing.
Edge Guards: Plastic or cardboard corner guards protect the vulnerable edges from dents.
Suspension Packaging: Rolls are suspended in wooden cases to avoid pressure damage during ocean freight."
