Nickel Alloy Copper Foils & Sheets C68700, C70600, C71500 for Roofing, Decoration

Description:

Elevate your industrial and architectural projects with our premium alloy copper sheets and foils, featuring an exceptional minimum copper purity of 99.99%. Sourced from the renowned Tisco brand in Jiangsu, China, this product line includes specialized grades like C68700 (Aluminum Brass), C70600 (Copper-Nickel 90/10), and C71500 (Copper-Nickel 70/30), renowned for their superior corrosion resistance, especially in marine environments. Supplied in various surfaces including a unique nickel-plated option, these sheets combine aesthetic versatility with robust performance. With an elongation of ≥35% and a tensile strength range of 220-400 MPa, they offer excellent formability for complex architectural designs while ensuring structural integrity. We support full customization in size, surface finish, and processing (bending, welding, cutting), with a low MOQ of 1 Ton and swift delivery, making us your ideal partner for high-quality metal solutions.

Q1: What is the key benefit of using Copper-Nickel alloys like C70600 and C71500?
Copper-Nickel alloys (e.g., C70600, C71500) offer exceptional resistance to corrosion by seawater, biofouling, and stress corrosion cracking. This makes them the premier choice for marine applications, including shipbuilding, offshore platforms, and desalination plants.

Q2: How does nickel plating enhance the copper sheet?
Nickel plating provides a hard, protective surface that significantly enhances corrosion and wear resistance. It also creates a bright, silvery, and non-tarnishing finish, which is highly sought after for decorative applications and provides a superior base for soldering.

Q3: With a 99.99% Cu content, is this product pure copper or an alloy?
This is an alloy. The 99.99% purity refers to the high base copper content used in the master alloy, but other elements (like Nickel, Aluminum, or Zinc) are added in specific proportions to create alloys like C71500 or C68700, which impart distinct mechanical and corrosion-resistant properties not found in pure copper.

Q4: What is your delivery time and payment terms?
Our standard delivery time is a swift 7-15 days. We require a 30% TT advance payment, with the remaining 70% balance paid before shipment. Samples are available upon request to ensure quality meets your expectations.

Q5: Can you provide custom sizes and surface finishes?
Yes, we specialize in customization. We can supply sheets in a vast range of thicknesses (0.1mm-500mm) and widths (up to 2500mm), and offer various surface finishes including mill, polished, bright, brushed, and mirror. Our in-house processing services can also pre-cut, bend, or punch parts to your exact specifications.
