Bar stock, also (colloquially) known as blank, slug or billet, [1] is a common form of raw purified metal, used by industry to manufacture metal parts and products. Bar stock is available in a variety of extrusion shapes and lengths. The most common shapes are round (circular cross-section), rectangular, square and hexagonal.
A billet is a length of metal that has a round or square cross-section, with an area less than 36 in 2 (230 cm 2). Billets are created directly via continuous casting or extrusion or indirectly via hot rolling an ingot or bloom. [1] [2] [4] Billets are further processed via profile rolling and drawing. Final products include bar stock and wire. [3]
Selecting the maximum forging temperature allows metals to be forged more easily, lowering the forging pressure and thus the wear on metal-forming dies. [2] The temperature at which a metal is forged can affect the homogeneity in microstructure and mechanical properties of forged products, which can highly affect the performance of products ...
Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...
Thixocasting utilizes a pre-cast billet with a non-dendritic microstructure that is normally produced by vigorously stirring the melt as the bar is being cast. Induction heating is normally used to re-heat the billets to the semi-solid temperature range, and die casting machines are used to inject the semi-solid material into hardened steel ...
An aluminium alloy (UK/IUPAC) or aluminum alloy (NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper , magnesium , manganese , silicon , tin , nickel and zinc .
6061 aluminium alloy (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements.
The 2019 facelift of the Opel/Vauxhall Astra K included a new 1.2 3-cylinder turbo with 110, 130 or 145 hp but this is not the PSA PureTech engine. This engine is part of GM’s E-Turbo range and had already been extensively developed at by GM for the 2019 Astra before PSA purchased the company. An all-new Astra, based on a PSA platform and ...
