Tellurium Copper Sheet

It s often used for transformer and circuit breaker terminals welding torch tips and fasteners.

Tellurium copper sheet.

Considered the best machining of the high copper alloys this copper tellurium alloy acquires strength from alloying tellurium. The high conductivity of tellurium copper makes it a suitable material for electrical applications and is an outstanding alloy for the production of hot forged products. The tellurium content typically ranges between 0 4 0 7 while the phosphorus content ranges between 0 004 0 12. Tellurium copper also referred to as alloy 145 alloy c15400 145 half hard tellurium and tecu is a copper based alloy that contains varying amounts of tellurium and phosphorus.

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. C109 cw118c is a free machining tellurium containing alloy that retains the high conductivity values associated with pure copper. 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.

Ensure adequate ventilation to maintain exposures below occupational limits. 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. 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.
