Bronze marks decoding in accordance with GOST 5017-74
Are you interested in decoding the brands of domestic bronzes, supplied in accordance with GOST 5017−74, from the supplier company AvecGlob? Here you will find the necessary information on this topic.
Application area
GOST 5017−74 applies to tin bronzes, processed by pressure and intended for the manufacture of semi-finished products in various industries and construction. The standard concerns bronzes of BrOF2−0.25, BrOTSS4−4-2.5, BrOTSS4−4-74, BrOF7−0.2, BrOF6.5−0.15, BrOF4−0.25, BrOTS4−3. At the same time, bronze grades of BrOF7−0.2; BrOF6.5−0.4; BrOF6.5−0.15 and BrOF4−0.25 due to copper, the mass fraction of zinc can be up to 0.3%, nickel 0.2%, which are not included in the total amount of impurities, which are not taken into account in the total amount of impurities. Accordingly, in bronze grades BrOF2−0.25, BrOTS4−3, BrOTSS4−4-25, BrOTSS4−4-4 due to copper, the nickel content can be up to 0.3%, which is not taken into account in the total amount of impurities.

Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
Decoding of brands and purpose of tin bronzes in accordance with GOST 5017−74
The results are given in the following tables, and take into account the conformity of bronze grades according to GOST and the Federal DIN standards.
| Requirements | According to DIN standard | According to GOST 5017−74 |
| Brands | CuSn2 | BrOF2−0.25 corresponds completely |
| CuSn8 | BrOF7−0.2-tin, phosphorus, lead impurities | |
| CuSn6 | BrOF6,6−0,15-toughened the content of tin, phosphorus, lead impurities | |
| CuSn4 | BrOF4−0.26-the content of tin, phosphorus, impurities of lead and iron is toughened | |
| CuSn4Zn3 | The concentration of tin, phosphorus, lead impurities is toughened | |
| CuSn4Zn4Pb3 | BrOTSS4−4-2,6-corresponds completely | |
| CuSn4Zn4Pb4 | BrOTSS4−4-4-corresponds completely | |
| The iron content | In alloys used to make articles with antimagnetic properties, the iron content should not exceed 0.02% | Corresponds completely |
| Nickel content | The content of nickel is allowed up to 0.3% | Corresponds to the part of brands BrOTS4−3, BrOTSS4−4-2,5, BrOTSS4−4-4, BrOF2−0.25 |
| Content of tin | In the alloy of the mark, the content of tin is allowed up to 7.5% | Corresponds completely |
| Brands | Characteristic properties | |
| according to GOST 5017−74 | according to DIN standard | |
| BrOF7−0.2 | CuSn8 | Are processed by cutting, high wear resistance, high corrosion resistance, good spring properties, suitable for soldering and welding |
| BrOF6.5−0.15 | CuSn6 | |
| BrOF4−0.25 | CuSn4 | Well processed by cutting, suitable for soldering and welding, corrosion-resistant |
| BrOF2−0.25 | CuSn2 | It is well processed by cutting, it is suitable for soldering and welding |
| БрОЦ4−3 | CuSn4Zn3 | It is processed by cutting, good spring properties and antifriction properties, corrosion-resistant, suitable for soldering |
| BrOTSS4−4-2.5 | CuSn4Zn4Pb3 | Are processed by cutting, good antifriction properties, corrosion-resistant, suitable for soldering |
| BrOTSS4−4-4 | CuSn4Zn4Pb4 | |
