Preparation method of copper alloy spectral standard sample

[0019] The weight content of each element in the copper alloy spectral standard sample is:

[0020] Si 0.10±0.01% Ni 4.5±0.2% Fe 0.02±0.002% Pb 0.005±0.001% Mn 0.05±0.006% Sn 0.50±0.03% Al 0.040±0.01% Zn 1.50±0.1%

[0021] (1) Material preparation: Calculated by 50Kg thrown into the furnace. 37.008Kg of pure metal copper, Cu-Si (20% by weight of Si) 0.25Kg, 10.598Kg of Cu-Ni (21.23% by weight of Ni), 10.598Kg of Cu-Mn (20% by weight of Mn content of 31.58%) 0.079Kg, Cu-Fe (the weight percentage of Fe is 4.34%) 0.230Kg, Cu-Zn (the weight percentage of Zn is 49.47%) 1.516Kg, Cu-Al (the weight percentage of Al content of 32.2%) 0.062Kg, pure Pb 0.0025Kg, pure Sn 0.25Kg;

[0022] (2) Melting: High-frequency furnace is used, and the melting temperature is 1130~1170°C. After the oven, according to the proportion of each element and the degree of oxidation difficulty, the order of feeding is to add copper + charcoal first, and then add Cu-Si to dissolve→Cu-Ni to dissolve→Cu-Mn to ...

[0027] The weight content of each element in the copper alloy spectral standard sample is:

[0028] Si 0.25±0.02% Ni 1.0±0.06% Fe 0.04±0.005% Pb 0.010±0.002% Mn 0.20±0.02% Sn 0.02±0.01% Al 0.010±0.002% Zn 0.10±0.02%

[0029] Get the raw materials ready: in embodiment 2, use pure metal copper 46.09Kg, Cu-Si (the weight percent composition of Si is 20%) 0.625Kg, Cu-Ni (the weight percent composition of Ni is 21.23%) 2.355Kg, Cu -Mn (31.58% by weight of Mn) 0.317Kg, Cu-Fe (4.34% by weight of Fe) 0.461Kg, Cu-Zn (49.47% by weight of Zn) 0.101Kg, Cu-Al (the weight percentage of Al is 32.2%) 0.016Kg, pure Pb 0.005Kg, pure Sn 0.010Kg;

[0030] Melting, ingot casting, homogenization treatment and wagon steps are the same as in Example 1.

[0032] The weight content of each element in the copper alloy spectral standard sample is:

[0033] Si 0.50±0.05% Ni 2.10±0.2% Fe 0.10±0.25% Pb 0.020±0.002% Mn 0.10±0.02% Sn 0.010±0.01% Al 0.005±0.001% Zn 0.05±0.002%
