I search for Nichrome plate long time, and successfully bought it from Ohmalloy material. OHMALLOY provide real good service in alloy service and can always help me in finding the correct resistance alloy.

—— Mike Harness

OHMALLOY can provie me only 1kg Kovar alloy wire 1.0mm with short time, that is really amazing. Thanks

—— Janey

Really professional in thermocouple wire and cable, what i want just can get from OHMALLOY

—— Chris

Enamelled Constantan 0.08mm, i never expect to get only 2kg of it. But OHMALLOY supply it to me with good quality. God Jesus! Such a reliable supplier from china

Jumper resistors(sampling resistors)are produced by CNC automatic computerized molding machine from precision resistance alloy materials. It exhibits small resistance, high precision, high-frequency and non-inductive characteristics. It can be widely used in computers, printers, inverter-aided air conditioners, power amplifiers, power suppliers, automatic instrumentation and other fields. Currently available: various forms of jumper resistors of 1~3W 0.002-0.10Q, and at the same time we provide designing according to customer requirements.
