Tombac
Tombac, or tombak, is a brass alloy with high copper content and 5–20% zinc content. Tin, lead or arsenic may be added for colouration. It is a cheap malleable alloy mainly used for medals, ornament, decoration and some munitions. In older use, the term may apply to brass alloy with a zinc content as high as 28–35%. Etymology The term ''tombak'' is derived from ''tembaga'', an Indonesian/ Malay word of Javanese origin meaning 'copper'. ''Tembaga'' entered Dutch usage concurrent with their colonisation of Indonesia. Likely, the term was used generically to describe Indonesian high-copper brass items, including gamelan gongs. It is one of the very few Indonesian loan words used in English or German. Common types * Modern CuZn15 (DIN: CuZn15 ; UNS: C23000 ; BS: CW 502L (CZ 102) ; ISO: CuZn15) – tombak with a gold colour, very good for cold forming, suitable for pressing, hammering, or embossing * modern CuZn12 (not standardized) – same characteristics and applicat ...

Brass
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally copper and zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, a copper alloy that contains tin instead of zinc. Both bronze and brass may include small proportions of a range of other Chemical element, elements including arsenic, lead, phosphorus, aluminium, manganese and silicon. Historically, the distinction between the two alloys has been less consistent and clear, and increasingly museums use the more general term "list of copper alloys, copper alloy". Brass has long been a popular material for its bright gold-like appearance and is still used for drawer pulls and door handle, doorknobs. It has also been widely used to ma ...

Hilt
The hilt (rarely called a haft or shaft) is the handle of a knife, dagger, sword, or bayonet, consisting of a guard, grip, and pommel. The guard may contain a crossguard or quillons. A tassel or sword knot may be attached to the guard or pommel. Pommel The pommel ( Anglo-Norman "little apple") is an enlarged fitting at the top of the handle. They were originally developed to prevent the sword from slipping from the hand. From around the 11th century in Europe, they became heavy enough to be a counterweight to the blade. This gave the sword a point of balance not too far from the hilt, allowing a more fluid fighting style. Depending on sword design and swordsmanship style, the pommel may also be used to strike the opponent (e.g. using the Mordhau technique). Pommels have appeared in a wide variety of shapes, including oblate spheroids, crescents, disks, wheels, and animal or bird heads. They are often engraved or inlayed with various designs and occasionally gilt and moun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Embossing (manufacturing)
Sheet metal embossing is a metalworking process for producing raised or sunken designs or relief in sheet metal. In contrast to coining (which uses unmatched dies), embossing uses matched male and female dies to achieve the pattern, either by stamping, or by passing a sheet or strip of metal between patterned rollers. It is often combined with foil stamping to create a shiny, 3D effect. Process The metal sheet embossing operation is commonly accomplished with a combination of heat and pressure on the sheet metal, depending on what type of embossing is required. Theoretically, with any of these procedures, the metal thickness is changed in its composition. Metal sheet is drawn through the male and female roller dies, producing a pattern or design on the metal sheet. Depending on the roller dies used, different patterns can be produced on the metal sheet. The pressure and a combination of heat actually "irons" while raising the level of the image higher than the substrate to m ...

Hammer
A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nail (fastener), nails into wood, to shape metal (as with a forge), or to crush Rock (geology), rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, war hammer, warfare, and mallet percussion, percussive musicianship (as with a gong). Hammering is use of a hammer in its strike capacity, as opposed to pry bar, prying with a secondary claw or grappling with a secondary hook. Carpentry and blacksmithing hammers are generally wielded from a stationary stance against a stationary target as gripped and propelled with one arm, in a lengthy downward plane (geometry), planar arc—downward to add kinetic energy to the impact—pivoting mainly around the shoulder and elbo ...
