Embodiment Construction

[0048] The present invention is described in further detail below in conjunction with specific embodiment:

[0049] The raw materials in Examples 1 to 41 of the present invention (the specific alloy composition and properties are shown in Table 1) use conventional copper, aluminum, iron, manganese, zinc, cobalt and other elements as raw materials, and are melted by induction furnace under industrial scale conditions , the melting temperature is 1150 ℃ ~ 1400 ℃, and then semi-continuous casting (or continuous casting) into aluminum bronze round (flat) ingots, the casting temperature is 1200 ℃ ~ 1300 ℃, if hot extrusion is required, the extrusion temperature 700°C~850°C. If forging is required, the forging temperature is 700°C~850°C, and then machining is performed to prepare products of different specifications and states.

[0050] The comparative examples of the present invention are aluminum bronzes of C63000 and US1961012510419610719.

[0051] The specific chemical composit...

Abstract

The invention discloses an aluminum bronze. The aluminum bronze comprises the following components in percentage by weight: 9.0-18.0% of aluminum, 2.0-7.0% of iron, 1-5% of manganese, 0.01-1% of zinc and the balance of copper and inevitable impurities. The aluminum bronze has the following advantages that through utilizing specific element ratio, specific processing mode and composition, the tensile strength of the aluminum bronze can reach above 700 MPa, the Brinell hardness (HB) of the aluminum bronze is 300-400, and the compressive strength of the aluminum bronze is above 1000MPa; the aluminum bronze has high wear resistance; the friction coefficient of the aluminum bronze is less than 0.15, so that scratched products and adhered products cannot be caused; the alloy has good hot working character; the alloy has high anti-softening temperature; and the aluminum bronze is not added with noble elements such as Ag and Ni, does not need to be thermally treated, and the raw material and production costs are lowered.

Description

technical field [0001] The invention relates to the field of alloys, in particular to an aluminum bronze with high strength, high hardness, high wear resistance, high compression resistance, excellent thermal processing performance and low cost and a preparation method thereof. Background technique [0002] Stainless steel products have the advantages of corrosion resistance, high temperature resistance, beautiful and bright appearance, etc. They are widely used in various sectors of the national economy, and a large part of them are stretched parts. However, stainless steel has high strength, large hardening index n value, sensitive deformation hardening, high resistance to tensile deformation, and has the characteristics of toughness, stickiness, and easy scratching. Higher requirements are put forward for the materials used in dies such as drawing dies and punches, that is, the die materials must not only have high strength and high hardness, but also have good wear resis...
