The core performance of an electrical device, like how well it switches, how long it lasts, and how safe it is — most depends on the quality of the contact material. If you have a contact tip that resists welding and has low resistance,high electrical conductivity, then your device will last much longer.
As an ISO certified global supplier, SHZHJ provides the excellent electrical performance solid or bi-metal contact plates or sheets.
According to your application, we can help you customize various silver contacts.
What SHZHJ Offers
Choose the Right Silver Alloy for Your Application:
Depending on the operating environment and device, you can choose the right silver alloy material. For low-current relays and thermostats, we have AgNi (Silver-Nickel) with good conductivity and lower cost. For DC contactors, we also have AgSnO2In2O3 with good anti-welding and long electrical life, and AgWC / AgC material is also popular with its anti-oxidation and very strong resistance to welding, so most of clients choose it to use for their high-voltage devices.
Our Internal Oxidation Process with better Performance:
Besides the material, we also have strength on the process.For the production of the silver alloy tips, the internal oxidation process basically creates fine, scattered oxide particles that bond really tightly with the silver. This gives the sheet contacts a nice, uniform, and dense structure. They resist arc erosion well, keep contact resistance low and steady, and have good anti-welding performance. It also increases hardness and tensile strength without hurting workability. So overall, it really boosts electrical life and makes the device more reliable.
Precision Rolling for Consistent Quality:
We use precision rolling to keep thickness within ±0.01mm(or according to your tolerance) and good flatness of the silver alloy sheets , so it's easy for automated production and high-volume contact manufacturing, produce strong, no peeling. Good performance with lower cost.
So if you want your electrical devices to last longer and work better, go with SHZHJ and make the performance silver electrical contact . We've got the right materials, the right process, and the right quality. Contact us for samples or a quote — let's get started.
