Import Bimetal Strip — Buy in Bulk from Supplier in China

Shanghai Baofang Metalic Mutilayer Materials Co., Ltd. manufactures bimetal strip using multilayer cladding technology for thermal-management and electromechanical switching applications. The strips combine two dissimilar metals with distinct thermal expansion coefficients, producing predictable deflection across a defined temperature range. Available dimensions are customisable rather than fixed to a catalogue, with thickness and width produced to project-specific requirements. The supplier indicates high thermal conductivity and corrosion resistance as characteristic properties, though exact conductivity values and alloy pairings are not itemised. The material is intended for environments requiring reliable temperature response and mechanical durability under cyclic thermal loading.

The thermal bimetal construction typically bonds a low-expansion alloy (such as iron-nickel Invar-type material) to a high-expansion alloy (such as brass, nickel-iron-manganese, or stainless steel) through roll-bonding and diffusion annealing. This creates a metallurgically bonded interface without filler material, ensuring consistent flexural response over thousands of thermal cycles. Resistivity, specific deflection (K factor), and maximum operating temperature depend entirely on the alloy pairing selected. Standard industry practice references ASTM B388 for thermostatic bimetal strip, which specifies deflection temperature response, electrical resistivity, and permissible variation in specific deflection. Shanghai Baofang does not state which alloy combinations they offer, so buyers must specify their thermal response curve and electrical requirements.

Primary applications include temperature sensors, bimetallic thermostats, thermal overload relays, and circuit breaker trip mechanisms. Automotive sector demand covers engine cooling system controls and HVAC climate regulation components. Aerospace applications include fuel system thermal protection and avionics temperature compensation. The supplier indicates suitability for HVAC industry controls, where bimetal elements drive damper actuation or compressor cycling. Customisable dimensions allow integration into existing tooling for electromechanical switch manufacturers. Importers should define their required specific deflection, maximum service temperature, and any electrical conductivity needs before requesting quotation, as these parameters determine alloy selection and strip geometry.

Shanghai Baofang Metalic Mutilayer Materials Co., Ltd. is located at 268 Chunyu Road, Huangdu Town Industrial Area, Jiading District, Shanghai 201804, placing them within Shanghai's northwestern industrial corridor. The supplier holds both Imported and Harbor trust tier designations on the platform. Their response rate is recorded at 0.00 percent with zero average response hours, indicating either a new listing, a dormant account, or incomplete metric collection. No information is provided about year of establishment, factory floor space, employee count, annual turnover, export licence details, or named customer references.

The company's product positioning centres on customised multilayer metal materials rather than standardised catalogue items, suggesting a made-to-order or project-engineering business model. The Jiading District location offers proximity to Shanghai's automotive and electronics manufacturing clusters, potential end-user industries for thermal bimetal components. Buyers should note that the listing contains no ISO certification mentions, no quality management system credentials, no patent disclosures, and no laboratory accreditation details. All production capabilities, quality control procedures, and technical staff qualifications should be verified through direct inquiry and, where possible, third-party audit before committing to production orders.
