Simple introduction for single crystal copper

Single crystal copper rod, 8 mm in diameter, was successfully produced using self-designed horizontal continuous casting equipment. Experimental results showed that the single crystal copper rod with mirror-like surface can be obtained on condition that the temperature of the mould was 1373 ∼1473 K and the casting speed was 20∼30mm/min. The crystallization orientation was [100] and the crystallization face was (200). The mixed crystals (equiaxed and columnar grains) on the rod surface were formed when the mould temperature was lower than the melting temperature(Tm<1356K) in the solidification front and the traction rate increased. Compared with those of unidirectionally solidified polycrystal copper rods, the tensile strength and the yield strength of the single crystal rod decreased by 8. 82% and 91. 62%, respectively, while the elongation and the reduction of cross-section area increased by 24.98% and 3.09%, respectively .

Single crystal copper properties :

CCSC technology with only one drawn copper grains , with extraordinary machining performance and electrical characteristics. There are three characteristics :

a single crystal copper purity 99.9999% ;

b resistance by 8% to 13% lower than the average copper ;

c. high toughness , ordinary copper twist on lap 16 that is broken , single-crystal copper can reverse 116 laps.

Quality Characteristics

Single crystal copper can eliminate the signal attenuation source created at crystalline interface therefore possess excellent audio features. With excellent electric and signal transmission capability, coupled with good manufacturing plasticity (with elongation ratio increases more than 2 times), significant stress fatigue resistance (with surface rate reduction increases more than 4 times) whereas it still does not suffer defects resulted from crystal segregation, gas hole, cavity shrinkage and pressure roll, in addition it enhances the glossy and flawless surface quality.
