It is made from carbon fibre because it is lighter so it will stay in the air for longer
COPPER! also aluminium, Carbon Steel, Gold and Iron
carbon steel, carbon fiber, they are light weight, strong and fairly inexpensive
no carbon steel not attract to magnets
Standard steel thickness 0.0179 of an inch. Galvanised steel is 0.0217 of an inch and aluminium 0.0159 of an inch
Steel is a conductor, because it is a metal and most metals are good conductors of heat, like iron, aluminium, copper, silver, stainless steel etc.
Usually different metals. Aluminium alloy hub and rim, stainless steel spokes and steel axle and bearings. But there can be steel rims and steel hub bodies too, as well as carbon fiber rims and carbon fiber hubs. Carbon fiber or aluminium spokes does happen, but is rare.
usually aluminium, but steel and carbon fiber can also be sued.
Initial javelins were made of wood until the mid-1950's. Dick Held improved javelin aerodynamics and durability by introducing aluminum javelins around that time (his brother, Bud, was the world-record holder for a time). Current javelins are made of steel, aluminum and/or carbon fiber.
carbon fiber costs more than steel
Steel Aluminium Carbon Fibre Titanium.
Usually Stainless steel. Expensive ones may be made out of aluminium or carbon fiber. Really cheap ones out of galvanized steel. You can get string-like Kevlar ones too, intended for field repairs.
I believe Aluminium = 2.7, and Carbon Steel = 7.85
Cheaper ones will have steel parts, average ones will have parts of aluminium alloys, Expensive ones can have carbon fiber or even titanium parts.
Usually stainless steel and/or carbon steel, with some newer firearms having carbon fiber parts.
yes its stronger than steel
Most adult sized bicycles these days have aluminium alloy handlebars, or even carbon fiber. Aluminium bars may be anodized, but will usually not be anodized. BMXes, Dutch bikes Townies and cruisers may have steel bars which usually are chromed.If it's high quality, they would have had a copper layer first, to help the chrome stick to the bar.
Usually an aluminum alloy, although high-end ones may be of titanium.
