This paper analyzes the necessity of applying the insulation copper-tube bus in the substation, compares the copper-tube bus with rectangle bus and aluminum manganese alloy conductor, and expounds the theoretical calculation of the insulation copper-tube bus.

The solid-liquid mixed casting of Al-Mn allays was studied by adding same alloys powder, the structure and performance of the material prepared by solid-liquid mixed casting was analyzed.

In this paper, a spectrophotometry for determination of manganese in high resistance aluminum manganese alloy is reported.

Molten salt electroplating processing of Al-Mn alloys and properties of coating had been investigated in this paper.

The microstructure and mechanical properties of as-cast and homogenized 3003 aluminium-manganese alloys grain-refined by Ti addition using different methods were investigated by SEM and EDS.

Deoxidising high quality aluminium killed steel with silicon-free ferroaluminium-manganese instead of purd aluminium exists some problems such as the production cost is increased,steel quality is impaired etc.
