Abstract
Description
Technical Field
[0001] The utility model relates to a metal coated wire, in particular to a brass coated wire. Background Art
[0002] At present, traditional bag chains and other accessories are usually made of expensive wire materials such as brass. On the one hand, due to the high density of brass, the weight of the entire bag chain is relatively heavy; on the other hand, the price of non-ferrous metal materials has risen rapidly in recent years, increasing the cost of bag chains. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a brass-clad wire which can reduce the amount of brass used and has the brass texture in appearance.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a brass coated wire, comprising: a light core wire, the cross section of the light core wire is a perfect circle, and the light core wire is coated with a brass layer;
[0005] Assume that the thickness of the brass layer is t1 and the density is ρ1, the radius of the lightweight core wire is R and the density is ρ2, K1 is the mass ratio of the brass layer to the brass coated wire per unit length,
[0006] but:
[0007] Among them: the unit of density is g / cm3, and the unit of thickness and radius is mm.
[0008] As a preferred solution, in the brass coated wire, the value range of K1 is [0.31, 0.68].
[0009] As a preferred solution, in the brass coated wire, the density ρ1 of the brass layer: the density ρ2 of the lightweight core wire≥3.208.
[0010] As a preferred solution, in the brass coated wire, the density ρ1 of the brass layer: the density ρ2 of the lightweight core wire≥3.246.
[0011] As a preferred solution, in the brass coated wire, the density ρ1 of the brass layer: the density ρ2 of the lightweight core wire≤3.303.
[0012] As a preferred solution, in the brass coated wire, the lightweight core wire is an aluminum core wire.
[0013] The beneficial effects of the utility model are:
[0014] 1. The utility model calculates the thickness of the brass strip (brass layer) used for coating according to the coefficient K1, i.e., the mass ratio of the brass layer to the entire coated wire material, and the wire diameter of the selected aluminum core rod (aluminum core wire), thereby greatly shortening the design cycle and reducing the design cost.
[0015] 2. The utility model forms a brass-coated wire by coating relatively cheap and lightweight metal wire with brass. Thus, the ornaments made of the brass-coated wire retain the texture of brass in appearance, and reduce weight and cost.
[0016] 3. The utility model further reduces the cost of brass coated wire by coating brass on relatively cheap and readily available aluminum core wire to form brass coated wire, thereby further reducing the cost of finished products such as accessories made therefrom. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 It is a schematic diagram of the cross-sectional structure of the brass coated wire described in the utility model.
[0018] Figure 1 The reference numerals in the figure are: 1, aluminum core wire, 2, brass layer; R is the radius of the aluminum core wire, t1 is the thickness of the brass layer, ρ1 is the density of the brass layer, and ρ2 is the density of the aluminum core wire. DETAILED DESCRIPTION
[0019] The specific implementation scheme of the brass coated wire described in the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] Assume that the thickness of brass layer 2 is t1 and its density is ρ1, the radius of aluminum core wire 1 is R and its density is ρ2, K1 is the mass ratio of brass layer 2 to brass coated wire (aluminum core wire 1 + brass layer 2) per unit length, and its value range is [0.31, 0.68].
[0022] but:
[0023] The unit of density is g / cm3, and the units of thickness and radius are mm; and the density ρ1 of the brass layer 2: the density ρ2 of the aluminum core wire 1 should be greater than or equal to 3.208, and preferably greater than or equal to 3.246; and less than or equal to 3.303.
[0024] In the production process of the brass coated wire of the utility model, the brass coated wire of the utility model can be formed by coating a brass strip on an aluminum alloy rod, and then the wire diameter is reduced to a required wire diameter by drawing and tempering. The aluminum alloy rod comprises, by mass percentage, 0.0041-0.0043% manganese, 0.0023-0.0027% magnesium, 0.1834-0.2034% copper, 0.0425-0.0445% silicon, 0.932-1.132% iron, 0.0116-0.0136% titanium, ≤0.006% zinc, ≤0.005% nickel, ≤0.0015% chromium, and ≤0.002% other impurity elements, with the balance being aluminum.
