Example Embodiment

[0020] The present invention is described in further detail below in conjunction with specific embodiment:

[0021] The production process of the rod (plate) wire rod of chromium-zirconium copper alloy in the embodiment of the present invention is as follows:

[0022] Raw material preparation and batching - alloying treatment vacuum casting or non-vacuum protection melting casting - ingot soaking - extrusion (or hot working) - (or cold working) - solid solution - pickling - cold working - Aging—(or pickling—cold processing)—inspection of the finished package (see Figure 1).

[0023] Specifically, it can be expressed as follows: prepare raw materials and ingredients according to the chemical composition of the alloy, use alloying treatment and vacuum melting casting or non-vacuum protection melting casting method to melt low calcium boron chromium zirconium copper alloy, so that chromium, zirconium, calcium, boron, etc. and copper form The master alloy is melted rapidly and ev...

Abstract

The invention discloses a low-calcium boron-chromium-zirconium-copper alloy with high strength and high electrical conductivity and a preparation method thereof. The chemical components of the alloy are: 0.2-1.5wt percent of chromium, 0.02-0.3wt percent of zirconium, 0.0003-0.05wt percent of calcium, 0.0003-0.04wt percent of boron and 0.01-0.5wt percent of other components, wherein, other components are at least one of the elements of: galvanized iron, zinc, silicon, tin, niobium, antimony, bismuth and lead; the rest is copper and inevitable impurities. The preparation method comprises: alloy smelting, thermal extrusion with severe deformation, multilevel thermal treatment and multistage aging under the temperature between 320 DEG C and 480 DEG C for 1-6 hours. The obtained alloy is characterized by high intensity, high conductivity, high softening point, good wear-resistance performance, good welding ability and formability, which is applicable to the manufacturing field such as automobile, high speed train, household appliances, aerospace, electronic telecommunication, metallurgical continuous casting, motor, injection precision mold, etc.
