Our company has been focusing on the production of automotive relay
moving spring assemblies for many years. Automotive relays are
widely used in automotive power systems, safety systems, chassis
systems, driving information systems, body systems, anti-theft
systems, and convenience environments.
The automotive relay moving spring assembly consists of three
parts: an armature (copper plated), a moving spring, and a silver
Place of Origin
New Energy EV Relay Stamping Parts
DT4E Pure iron and C7025-TM02 copper alloy
CAD,3D,Solid works or others
Carton or as customer’s requirement
Pickling, grinding, plating, heat treatment, etc.
The automotive relay riveting assembly is composed of an armature,
a moving spring, and a silver contact.
1. The moving spring is made of C7025TM02 copper alloy. It is a
high-precision zinc-nickel-copper strip with excellent cold and hot
workability, ductility, corrosion resistance, fatigue resistance,
luster beauty, high elasticity, electrical and mechanical
properties, shielding and other properties. Structural parts,
elastic components, precision instruments, communications industry,
liquid crystal oscillator housings, potentiometer reeds, and
electrical materials that work in wet and corrosive media.
2. The armature is made of high quality DT4E pure iron. The
industrial pure iron is particularly soft, with high toughness and
good electromagnetic properties. As an electromagnetic material, it
has high magnetic permeability and low magnetic resistance. It is
widely used in electronic and electrical, electrical components,
magnetic materials, amorphous products, relays, sensors, automotive
brakes, textile machinery, electric meter solenoid valves and other
The melting point is higher than iron, it is harder to rust in the
humid air than in iron, and it can be passivated in cold
concentrated sulfuric acid.
1. Good gloss, smoothness and beauty.
2. keep the accuracy and accurate size;
3. The highest stamping efficiency is up to 180 strokes per minute.
4. The Riveting Electrical Contact's tolerance can be control in
±0.02 assured by high speed precision stamping die.
5. in-mold automatic riveting, improve the stability of product
