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 applications as Cu ...

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of English Words Of Indonesian Origin
The following is a partial list of English words of Indonesian origin. The loanwords in this list may be borrowed or derived, either directly or indirectly, from the Indonesian language. Some words may also be borrowed from Malay during the British colonial period in British Malaya, or during the short period of British rule in Java. However, unlike loanwords of Malay origin, some of these loanwords may be derived from languages of Indonesia such as Javanese, Sundanese, Minangkabau, Buginese, Makassarese, Acehnese, and many more. Examples of English loanwords of Indonesian origin are those related to Indonesian culture and artforms (e.g. angklung, batik, kris and wayang), as well as words used to describe flora and fauna endemic to the Indonesian archipelago (e.g. babirusa, cockatoo, orangutan and Komodo). Other recently adopted loanwords include food related terms (e.g. agar and tempeh) and specific volcanology terms (e.g. lahar and ribu). Animals * Babirusa, compound ...

Hilt
The hilt (rarely called a haft or shaft) of a knife, dagger, sword, or bayonet is its handle, 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 mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Embossing (manufacturing)
Sheet metal embossing is a stamping process for producing raised or sunken designs or relief in sheet metal. This process can be made by means of matched male and female roller dies, or by passing sheet or a strip of metal between rolls of the desired pattern. 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 make it smooth. The term "impressing" refers to an image ''l ...

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 nails into wood, to shape metal (as with a forge), or to crush rock. Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. Traditional disciplines include carpentry, blacksmithing, warfare, and percussive musicianship (as with a gong). Hammering is use of a hammer in its strike capacity, as opposed to 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 planar arc—downward to add kinetic energy to the impact—pivoting mainly around the shoulder and elbow, with a small but brisk wrist rotation shortly before impact; for extreme impact, c ...
