  • Tellurium copper Wikipedia

    Tellurium is usually added to copper to improve machinability ("free cutting"). ASTM specification B301 has 0.5% tellurium; at concentrations of up to 0.75% machinability is improved whilst electrical conductivity and hot working behavior is maintained. Mechanical properties are similar to tough pitch copper, whilst machinability is similar to brass the alloy's hardnesses are increased by precipitation of copper telluride.

  • Tellurium Copper Alloy AMERICAN ELEMENTS

    Tellurium was discovered by Franz Muller von Reichenstein in 1782 and first isolated by Martin Heinrich Klaproth in 1798. In its elemental form, tellurium has a silvery lustrous gray appearance. The tellurium atom has a radius of 140 pm and a Van der Waals radius of 206 pm. Tellurium is most commonly sourced from the anode sludges produced as a byproduct of copper refining.

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.

  • Tellurium Copper (Alloy 145/C14500) Sequoia Brass &

    Alloy 145 Tellurium Copper (C14500) 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 tellurium content typically ranges between 0.4–0.7%, while the phosphorus content ranges between 0.004–0.12%.

  • Tellurium Copper McMaster-Carr

    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. It’s often used for transformer and circuit-breaker terminals, welding torch tips, and fasteners. For technical drawings and 3-D models, click on a part number.

  • Tellurium Corrosionsource

    Tellurium improves the machinability of copper and stainless steel, and its addition to lead decreases the corrosive action of sulfuric acid on lead and improves its strength and hardness. Tellurium is used as a basic ingredient in blasting caps, and is added to cast iron for chill control.

  • Tellurium Te PubChem

    Tellurium production is mainly a byproduct of copper processing. The 1960's brought growth in thermoelectric applications for tellurium, as well as its use in free-machining steel, which became the dominant use. The use of high-purity tellurium in cadmium telluride solar cells is very promising.

    The tellurium atom has a radius of 140.pm and its Van der Waals radius is 206.pm. Tellurium is most commonly sourced from the anode sludges produced as a byproduct of copper refining. Tellurium was first discovered by Franz Muller von Reichenstein in 1782. The name Tellurium originates from the Greek word 'Tellus' meaning Earth.

    24-06-2016· Tellurium occurs in relatively few minerals, including calaverite (AuTe2), sylvanite (AgAuTe4) and tellurite (TeO2), but it is commercially produced only as a by-product of refining other metals. Over 80% of tellurium production comes from the anode slimes from copper refining.

  • C145 / C14500 Tellurium Copper Swiss Machined Parts

    Tellurium copper alloy 145 (TeCu) is considered a free-machining copper alloy, ideal for parts that require extensive machining, corrosion resistance, or high conductivity. It produces short, clean chips that are easily removable. Tellurium copper machines more quickly and efficiently than pure copper.

    01-03-2015· Tellurium has a greater adverse effect on annealability of copper than selenium (Cooper, 1971). Therefore, the total combined concentration of tellurium, selenium and bismuth must be kept to less than 3 ppm in Grade 1 Electrolytic Copper Cathode ( ASTM B115-00, 2004 ) and therefore must be maintained well below 1 mg/L in the electrowinning electrolyte to achieve this level of purity.
