Connectors, Terminals & Spring Contacts places specific demands on the alloys that serve it. Jiangsu DZX Alloy supplies Beryllium copper, Chromium-zirconium copper, Platinum-iridium for this duty, combining 24+ years of precision-alloy manufacturing experience with an ISO9001 triple-inspection system, a 12,000 m2 self-owned factory and full batch traceability. Each duty inside Electronics & Semiconductors stresses the material differently, and connectors, terminals & spring contacts is no exception.
Precision resistors, transformer cores, magnetic shielding, IC lead frames, glass-to-metal seals and connectors require functional alloys with controlled electrical, magnetic and thermal-expansion behaviour. Jiangsu DZX Alloy supplies CuNi precision resistance alloys (6J8–6J40), soft magnetic alloys (1J79, FeNi50), controlled-expansion alloys (4J29 Kovar, Invar 36), beryllium copper and elastic alloys.
General Requirements for Connectors, Terminals & Spring Contacts
- Electrical stability: resistivity and TCR held within design windows, batch to batch.
- Magnetic control: permeability and core-loss behaviour documented per heat-treatment condition.
- Expansion matching: CTE matched to glass, ceramic or silicon counterparts for sealing and packaging.
- Precision dimensions: strip to 0.05 mm and wire to micrometre-level tolerances.
- Supply-form fit: materials must be available in the forms fabrication requires — typically strip, bar / strip, wire, bar / wire, tube.
Recommended Materials & Specifications for Connectors, Terminals & Spring Contacts
The following grades and specifications apply to this application; all values are as supplied by Jiangsu DZX Alloy with per-batch certificates:
| Material | Representative grades | Key properties | Available forms |
|---|---|---|---|
| Beryllium copper | C17200 | high strength, springs, electrical conduction | strip, wire, bar |
| Chromium-zirconium copper | C18150 | high-temperature contacts | strip, bar |
| Platinum-iridium | PtIr10, PtIr20 | precious-metalprecision contacts | wire, tube |
Beryllium copper (C17200) is specified for its high strength, springs, electrical conduction. Jiangsu DZX Alloy supplies it as strip, wire, bar, with dimensions produced to drawing; supported fabrication routes include bending, welding, stamping and machining as the form allows. Chromium-zirconium copper (C18150) is specified for its high-temperature contacts. Jiangsu DZX Alloy supplies it as strip, bar, with dimensions produced to drawing; supported fabrication routes include bending, welding, stamping and machining as the form allows. Platinum-iridium (PtIr10, PtIr20) is specified for its precious-metalprecision contacts. Jiangsu DZX Alloy supplies it as wire, tube, with dimensions produced to drawing; supported fabrication routes include bending, welding, stamping and machining as the form allows.
Available supply forms by grade:
- Beryllium copper: strip, wire, bar
- Chromium-zirconium copper: strip, bar
- Platinum-iridium: wire, tube
Customisation: Grades, diameters, wall thicknesses and lengths can be manufactured to customer drawings, and samples are available on request.
Application Scenario Deep Dive: Connectors, Terminals & Spring Contacts
In electronic components, the material is inside the measurement: a resistor element whose TCR drifts between batches forces per-batch compensation, and a core whose permeability wanders destabilises every sensor built on it. Per-batch electrical and magnetic verification converts the material from a variable into a constant.
When high strength, springs, electrical conduction governs the duty, Beryllium copper is the typical first call; Chromium-zirconium copper is preferred where high-temperature contacts matters more. Jiangsu DZX Alloy’s engineering team can review your duty conditions and confirm the grade, condition and tolerance before ordering.
Connectors, Terminals & Spring Contacts does not operate in isolation: within Electronics & Semiconductors it sits alongside Precision Resistors & Shunts, Magnetic Components & Shielding Cores, IC Packaging, Lead Frames & Glass-to-Metal Seals, and material choices made here often share grades, documentation and inspection practice with those duties. Reviewing the neighbouring application pages is the fastest way to see where specification boundaries lie.
