The results show that the microstructure of the cladding wire by drawing at room temperature is vimineous grain as fibril shape from prime equiaxed grain. The fibril diameter is in inverse proportion to deformation and the fibril length is in direct proportion to the square of deformation approximately. The ultimate tensile strength of the cladding wire by drawing at room temperature goes up in direct proportion to square root of deformation, whereas the elongation decreases and fluctuates.

结果表明：显微组织自原始的等轴晶变为细长条纤维状，纤维直径与形变量近似地成反比，纤维长度与形变量的平方近似地成正比；经室温拉变形的铜包铝线的极限抗拉强度随形变量增大而增大，与形变量平方根呈直线关系；延伸率随形变量增大逐渐降低，但延伸率波动较大。
