Copper Alloy Manganin Strip for Electronic Components

copper alloy manganin strip for electronic components

1.WHY CHOOSE WISDOM HIGH QUALITY MANGANIN ALLOYS?

All our raw material is made from prime material, not recycle material. We have more than 25 years experience in manufacturing resistance heating alloys.

In the market, not all the Manganin alloys are with standard chemical composition and stable resistance. Professional and reliable is the soul of our business.

2.DESCRIPTION OF Manganin ALLOYS:

It is the electric resistance alloy with the copper, manganese, nickel as the essential component. It is a superior precision resistor material with the characteristics of high electronic resistivity, very small resistance temperature coefficient, low Thermal EMF vs. Copper E and long-term stability. It is mainly applied in manufacturing heater resistances and resistance elements of standard resistor, precision instrument and so on.

3.WISDOM ALLOYS CHARACTERISTICS:

1)Manufactured according to international quality. System (ISO9001)

2)Stable resistance and long-life span

3)Mill test certificate will be provided after production

4)Size range wire:.0.018-10mm ribbons: 0.05-0.2*2-6mm strips: 0.05-5*5-250mm

5)Good packing methods to keep goods no damage during delivery

6)Customized lable, packing, OEM service

7)24 hours after-sale service
