Tellurium Copper Sheet

The copper telluride precipitations become finely dispersed throughout the matrix and assist in chip breakage into short pieces thus enabling a much higher machining speed than with pure copper.

Tellurium copper sheet.

Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Also called tellurium copper 145 copper contains tellurium which makes it more machinable than all other copper while maintaining good corrosion resistance and high electrical conductivity. Copper 145 tellurium has a machinability rating scale of 85 compared to pure copper of 20 thus ensuring longer tool life. Tellurium tellurium compounds as te 0 1 mg m 3 0 1 mg m 3.

Certificates with a traceable lot number are available for these products. C109 cw118c is a free machining tellurium containing alloy that retains the high conductivity values associated with pure copper. Considered the best machining of the high copper alloys this copper tellurium alloy acquires strength from alloying tellurium. The machining characteristics of the copper are significantly improved by alloying it with approximately half per cent of tellurium while the electrical and thermal conductivity are only slightly reduced.

As with all metals when reducing the amount of copper conductivity dramatically decreases yet strength increases. It s often used for transformer and circuit breaker terminals welding torch tips and fasteners. The tellurium content typically ranges between 0 4 0 7 while the phosphorus content ranges between 0 004 0 12. Copper 0 1 mg m 3 0 2 mg m 3.
