Titanium composite is a new type of metal material with high cost performance. There are many methods for processing titanium composite materials, and the industry often uses explosive welding complex 4 method, explosive welding + rolling composite method and extrusion composite method. The first two methods are used for the production of composite panels, and the latter method is mainly used for the production of composite rods and composite tubes.
Section 2 Conventional Compound Method
1. Explosive welding compound method and explosive welding + rolling compound method
The explosive welding technology of titanium composites has developed rapidly. It can not only produce titanium steel but also realize titanium-copper, titanium-nickel, titanium-steel-titanium, titanium-steel-stainless steel, titanium-niobium-stainless steel, titanium-copper-aluminum Production of a series of double-layer and multi-layer layered titanium 23: titanium alloy composite materials such as stainless steel. At present, through the explosive composite method, the composite wood t area can reach 25m2, the explosive + rolling composite method can reach 35m2, and the thickness of the M layer ranges from 1.2 to 12mm.
Second, the extrusion method
Extruded layered metal composite materials can be divided into two categories of coating materials and special layered M-composite materials. The coating materials can be further divided into solid coating materials and bimetallic tubes.
(1 Extruded solid clad material. The most common are various shapes of _ too copper composite rods (titanium-coated copper), etc., which is characterized by excellent electrical conductivity, resistance and high strength.
(2 Extruded bimetallic tube. Before extrusion, two hollow billets are assembled into a compound: combined billet, and then extruded. The cross-sectional shape of the titanium / steel composite tube is round, square, drum; shape, oblate, rectangular, etc. The diameter of the circumscribed circle: 4 ~ 80mm, the thickness of the cladding layer is not more than 0.8mm, and the length is not more than 6n ^. The composite pipe has good process performance and can be further plastic processed for expansion, bending, necking, etc.
