How our custom manufactured brass strips and multi-metal solutions drive technological advancements in critical global industries.
High-conductivity brass strips are essential for manufacturing terminals, spring contacts, connectors, and switchgears. Our precise metallurgical processes reduce internal stress, guaranteeing fatigue resistance and stability under electrical loads.
With the expansion of electric vehicles, the demand for highly reliable brass components has grown. Our materials are used in EV battery busbars, sensor housings, and radiator fins, offering excellent thermal dissipation and structural strength.
We combine advanced metallurgy with downstream custom fabrication services. Our facilities stamp, bend, and weld heavy-duty copper and brass enclosures designed to shield sensitive electronics from electromagnetic interference (EMI).
Navigating the global metal market requires technical expertise and supply chain stability. As a premier China-based brass strip supplier, Ningbo Puppet Steel manages raw material sourcing, LME-linked pricing models, and international logistics. Our manufacturing processes utilize vertical integration, from copper cathode smelting to cold rolling, ensuring price stability and reliable supply schedules.
Global buyer requirements vary based on regional environmental and structural mandates. We operate dedicated shipping networks servicing Europe, North America, Southeast Asia, and the Middle East. By coordinating container space and shipping routes directly from Ningbo Port, we ensure that our materials arrive on-schedule and in optimal condition.
Every shipment of brass strips is traceably linked to its original smelting batch. Comprehensive chemical analysis and mill test certificates (MTC) are supplied standard with all orders.

Operating in highly regulated global markets requires strict compliance with international manufacturing and material standards. At Ningbo Puppet Steel, we ensure all products meet RoHS, REACH, ASTM, and DIN requirements. This ensures our brass strips and steel fabrications integrate seamlessly into European, North American, and Asian production lines without regulatory delays.
We provide comprehensive documentation support, including Mill Test Reports, RoHS Compliance Certificates, and conflict-free mineral declarations. Our engineering team works directly with clients to assist with localization, modifying alloy chemistry and tempers to match precise project specifications.
Additionally, we offer customized packaging options such as vacuum sealing and anti-oxidation wrapping to prevent rust and degradation during long-distance ocean transport.
Demonstrating performance in specialized real-world settings across diverse markets.
Our brass strips serve as high-durability grounding terminals and grounding grids for solar farms and wind turbine controls in high-humidity offshore environments.
We fabricate high-precision copper enclosure assemblies to shield sensitive circuit cards in 5G telecommunication base stations, ensuring low signal interference.
Antimicrobial brass alloys are shaped into precise contact strips for surgical instruments and electrical interfaces in critical care hospital equipment.
The manufacturing landscape is shifting toward ultra-precision, digital integration, and carbon neutrality. Ningbo Puppet Steel continues to invest in technology to align with these industry standards.
Our developmental roadmap centers on two primary goals: producing ultra-thin brass strips (thicknesses ≤ 0.05 mm) with high fatigue life for micro-electronic connectors, and reducing carbon emissions in our metal melting processes.
By upgrading our annealing furnaces and utilizing digital thickness monitoring systems, we ensure consistent mechanical properties throughout entire coil lengths, minimizing waste for automated stamping plants.

Answers to common questions about materials procurement, alloy selection, and manufacturing capabilities.
Our standard manufacturing processes achieve thickness tolerances as tight as ±0.01 mm for thin-gauge strips, and width tolerances down to ±0.1 mm on precision-slit coils. We customize these parameters to meet your specific project design requirements.
Yes. All of our brass strips, copper alloys, and custom fabricated metal products fully comply with RoHS and REACH standards. We issue SGS or equivalent third-party material certificates to confirm chemical compliance and trace source metals.
We use robust packaging systems that include anti-oxidation paper, desiccant packs, and heavy-duty plastic vacuum sealing. Coils are secured on sturdy wooden pallets designed to withstand maritime transit humidity and structural shifts.
Absolutely. We manufacture brass strips in a wide range of tempers, including Annealed (O), 1/4H, 1/2H, Hard (H), Extra-Hard (EH), and Spring-Hard. Mechanical properties are verified using tensile and hardness tests to ensure consistency.
Our pricing model is linked to current London Metal Exchange (LME) or Shanghai Futures Exchange (SHFE) rates, combined with a fixed fabrication cost. We also offer options for spot purchasing or forward hedging contracts to manage cost volatility for major projects.
