Beryllium Copper UNS C17200 (also known as CuBe2, CW101C, or C17200 BeCu) is the most widely used beryllium copper alloy in the world. With a beryllium content of approximately 1.8–2.0%, it delivers a unique combination of ultra-high tensile strength (up to 1400 MPa after age hardening), excellent electrical conductivity (~22% IACS), outstanding fatigue resistance, and non-sparking, non-magnetic properties.
These characteristics make C17200 the material of choice for demanding applications across Spain's aerospace, defense, automotive, oil & gas, electronics, and precision tooling sectors. Whether you need beryllium copper rods, bars, plates, strips, tubes, or custom-machined parts, Sichuan Kepai New Materials Co., Ltd. is your reliable supplier and factory partner.

Spain ranks among Europe's top five industrial economies, with a robust manufacturing base in Cataluña, País Vasco, Madrid, and Comunitat Valenciana. The country's metal processing and precision engineering sectors consume significant volumes of specialty copper alloys annually, with demand for high-performance materials like C17200 growing at 6–8% per year.
Spain is home to major aerospace hubs including Airbus Spain (Getafe & Sevilla), Indra, and ITP Aero. These companies require non-sparking, non-magnetic beryllium copper components for aircraft tooling, landing gear fixtures, and avionics connectors — applications where C17200's unique properties are irreplaceable.
With SEAT, Volkswagen Group España, and Stellantis operating major plants across Spain, the automotive sector demands high-precision beryllium copper springs, connectors, and relay components. The rapid growth of EV production in Spain (targeting 300,000 EVs/year by 2030) is accelerating demand for C17200 in battery management systems and charging infrastructure.
Spain leads Europe in solar and wind energy capacity. Beryllium copper C17200 is widely used in solar inverter connectors, wind turbine slip rings, and high-frequency 5G base station components. As Spain rolls out its 5G network and expands renewable infrastructure, demand for reliable, high-conductivity copper alloys continues to surge.
Spain's Repsol and other energy companies operate refineries and offshore platforms where non-sparking tools made from C17200 beryllium copper are mandatory safety requirements. The alloy's resistance to corrosion, fatigue, and elevated temperatures makes it indispensable in hazardous environments throughout Spain's energy sector.
Barcelona and Madrid host thriving electronics manufacturing clusters. C17200 strips and foils are used in high-reliability connectors, semiconductor test sockets, precision springs, and medical device components. Spain's growing medtech sector (particularly in Cataluña and Madrid) is emerging as a significant consumer of beryllium copper precision parts.
Spain's commitment to electrification — with €4.3 billion invested in EV manufacturing through the PERTE VEC program — is creating massive new demand for beryllium copper components in battery relay contacts, high-current connectors, and thermal management systems. C17200's combination of high strength and conductivity makes it the preferred material for next-generation EV architectures.
European Green Deal regulations are pushing Spanish manufacturers toward materials with longer service lives and higher recyclability. Beryllium copper C17200 components typically last 3–5× longer than alternatives, reducing total lifecycle costs and environmental impact. Kepai's commitment to sustainable production aligns perfectly with Spain's industrial decarbonization goals.
Spain's plastics and rubber molding industry — centered in Alicante, Girona, and Guipúzcoa — is experiencing a surge in demand for beryllium copper mold inserts and cores. C17200's thermal conductivity enables significantly faster cycle times in injection molding, making it a critical productivity-enhancing material for Spanish toolmakers.
Post-pandemic supply chain disruptions have prompted Spanish industrial buyers to diversify their copper alloy sourcing beyond traditional European suppliers. Direct partnerships with certified Asian manufacturers like Kepai offer significant cost advantages (15–30% savings) while maintaining ISO-certified quality standards, making this an increasingly attractive procurement strategy for Spanish companies.
High-reliability connectors for Spain's telecommunications and railway infrastructure (Renfe, Adif), ensuring minimal signal loss and long service life.
Mandatory in Spanish petrochemical plants (Tarragona, Huelva), mining operations, and explosive material handling facilities where spark-free tools are legally required.
Beryllium copper mold cores used by Spanish automotive plastics suppliers reduce cycle time by up to 40%, dramatically improving production efficiency at facilities in Valencia and Zaragoza.
Ultra-high fatigue-resistant springs for electronic devices, medical equipment, and defense systems manufactured at Spain's precision engineering centers in País Vasco and Cataluña.
Contact springs and relay components for electric vehicle battery management systems produced at SEAT's Martorell plant and Volkswagen's Pamplona facility.
Non-magnetic, non-sparking tooling for Airbus España's composite manufacturing lines in Getafe and Puerto Real, where metallic contamination must be absolutely prevented.
Electrical contacts and slip rings for Spain's extensive solar farms (Extremadura, Castilla-La Mancha) and offshore wind projects (Canarias, Galicia).
Precision-machined beryllium copper components for diagnostic imaging equipment and surgical instruments produced by Spain's growing medtech industry in Madrid and Barcelona.
