In metal structural materials, there are various materials, shapes and sizes of rods, such as ordinary steel rods, alloy steel rods, stainless steel rods, titanium rods, copper rods and aluminum rods. The cross-section shapes of these bars are round, square, rectangular, diamond, plum and ellipse. Its size and size are varied and ever-changing. They are used as the rotating shaft and drive shaft, or as guide rods, connecting rods and supporting rods. According to their physical and chemical characteristics, or as corrosion-resistant, wear-resistant and heat-resistant parts, or as conductive materials, etc.
 
In many cases, the above rod-like structure material will be more suitable in the form of clad pipe-rod or clad rod-rod considering the use effect and cost reduction. For example, as a corrosion-resistant bar, stainless steel pipes and titanium pipes with ordinary steel rods constitute a composite pipe-rod. As a wear-resistant bar, a composite pipe rod made of wear resistant alloy pipe and ordinary steel bar is used. As a heat resistant bar, a composite pipe rod made of heat resistant alloy pipe and ordinary steel bar is used. The surface of these composite tubes and rods has promising and special physical and chemical properties, while the core has high strength and low cost characteristics. Therefore, it can not only meet the technical requirements, but also significantly reduce costs, and save a lot of rare and valuable materials.
   
Conductive rods working in corrosive medium have two technical requirements: corrosion resistance and conduction. This is the best of both worlds for single metal conductors. But if you use a composite pipe-rod consisting of corrosion-resistant metal pipes and metal bars with good conductivity, you can do both. Such as titanium - copper, titanium - aluminum, stainless steel - copper and stainless steel - aluminum clad pipe - bar. It is this kind of composite structure material. The former is pipe material, the latter is bar material, and the outer layer is corrosion resistant and inner conductive. This kind of Bimetal clad rod bar has been widely used in electrolysis, electroplating and power industry, and they have good performance.
 
The unique bimetal clad bar rod developed by Henan chalco is:
 
1. Three layer composite pipe rod: aluminum alloy pipe -BT1-0 pure titanium tube -12X18H10T stainless steel three layer clad pipe rod
2. Bimetal clad flat rod: titanium copper composite flat bar
3. Using small pieces of large-thickness clad plates, turning into clad rods (pipes) of different diameters, and then using them as butt-joint to connect rods (pipes) of different sizes of dissimilar metals.
4. Titanium steel clad pipe rod: corrosion resistant stirring shaft used to make
5. Titanium copper clad pipe rod: used for electrodes in electrochemical industry.
