High Quality ASTM B152 Copper Sheet
Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of high quality astm b152 copper sheet in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount high quality astm b152 copper sheet for sale here from our factory. Customized orders are welcome.
ASTM B152 is the definitive industrial standard for high-quality rolled copper products. At GNEE, we specialize in providing premium ASTM B152 copper sheets that meet the most rigorous demands of electrical, architectural, and industrial engineering.
Our copper sheets are produced using advanced cold-rolling processes to ensure a minimum copper purity of 99.9%. Whether you require the high conductivity of C11000 ETP copper or the superior weldability of C12200 DHP copper, our materials are certified to deliver consistent performance and durability in any environment.
Available Grades
C11000 (Electrolytic Tough Pitch - ETP): The universal choice for electrical components, offering 101% IACS conductivity.
C10100 & C10200 (Oxygen-Free): The highest purity copper (99.99%) for vacuum electronics and high-end audio.
C12200 (Phosphorus-Deoxidized): The preferred grade for roofing, flashing, and heat exchanger applications due to its excellent brazing properties.
Tempers: Available from Soft (O60) to Extra Hard (H04) to match your fabrication needs.
Applications
Electrical Power: Busbars, switchgear, transformer components, and grounding plates.
Architecture: Premium roofing, gutters, wall cladding, and interior ornamental trim.
Industrial Machinery: Gaskets, shims, precision stampings, and heavy-duty radiator cores.
Electronics: Printed circuit boards (PCBs), heat sinks, and electromagnetic shielding (EMI).
FAQ
Q1: What exactly does the ASTM B152 standard cover?
A: ASTM B152 is the standard specification for copper sheet, strip, plate, and rolled bar. It ensures that the material meets specific requirements for chemical composition, temper, and mechanical properties. At GNEE, our ASTM B152 copper sheets are primarily produced from high-purity electrolytic copper (99.9% Cu min), making them ideal for critical electrical and industrial applications.
Q2: What is the difference between C11000 and C12200 under ASTM B152?
A: This is a common question for engineers. C11000 (ETP Copper) is the "industry standard" for electrical applications due to its 101% IACS conductivity. C12200 (DHP Copper) is phosphorus-deoxidized copper; while its conductivity is lower, it has superior welding and brazing characteristics, making it the preferred choice for heat exchangers, condensers, and roofing. We supply both grades in full compliance with ASTM B152.
Q3: Can I order ASTM B152 copper sheets in different tempers?
A: Yes, we offer a wide range of tempers to suit your fabrication needs. Common tempers include O60 (Soft Annealed) for deep drawing and bending, H02 (Half-Hard) for general structural use, and H04 (Hard) for applications requiring higher strength and rigidity. All our tempers are strictly tested to meet the mechanical requirements of the ASTM B152/B152M specification.
Q4: Is ASTM B152 copper sheet suitable for outdoor architectural use?
A: Absolutely. ASTM B152 copper (especially C12200) is highly resistant to atmospheric corrosion. Over time, it develops a natural protective patina that transitions from a bright metallic finish to a deep brown and eventually a classic green. This makes it a "lifetime" material for premium roofing, gutters, and wall cladding.
