No other touch surface material has this kind of registration.
The effect of temperature on hardness and microstructure in rotary bending of copper sheets was investigated.
1 the anisotropy of young s modulus of copper sheet subjected to forward cold rolling to a reduction of 70 is determined primarily by the fourth harmonic of the expansion of the modulus curve.
In metalworking rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.
