Bronze is an alloy based on copper and tin doped with aluminum, silicon, beryllium, lead and other elements. These alloys are divided into deformable and casting. Casting is a technological process when a specially prepared form is filled with molten material. After cooling the resulting product undergoes further processing.
Varieties of bronze casting.
— in shell shapes;
— in sand molds (machine or hand moulded);
— investment casting;
— gravity die casting;
— burned products;
— vacuum casting;
Principal cast bronze
Bronze tin — Bro10f1, Bro8c4, Bro5c5s5, Bro4c4s17, БрО10Ц10, etc. High casting quality tin bronzes — their main advantage. They melt at a relatively low temperature, during casting gives minimal shrinkage than favorably with other alloys. Ideally suited for casting complex shapes.
Bronze aluminum — Bra9mc2l, Bra9zh3l, Bra10zh4n4l, Bra10zh3mc2 etc. They are inferior to tin bronzes for casting qualities, give a greater percentage of shrinkage, but it is not formed porosity. Castings are more dense with high specific strength. Doping with phosphorus improves their castability.
Cast blanks have the form of forgings, which after quenching with vacation delivered the required categories of strength (KP) according to GOST 8479−70. Forgings have a relatively rough approximation to the shape of the finished product, which requires minimal machining. Constructive economic shape forging enables the production of workpieces with highest performance and less waste. Get centrifugal casting bronze casting (rings, bushings, bearings, wheels, wreaths) weighing up to 2 tons and sections up to 1500 mm. They are supplied with a predetermined allowance. Casting, get burnt out models and chill method (sliders, breadcrumbs, flat parts, thrust bearings, etc.) weighing up to two tons and dimensions up to 2000 mm. Brand of bronze comply with the requirements of GOST 613−79, GOST 493−79.
