770 MPa Tungsten Alloy Rivets
Tungsten Heavy Alloy Rivets are a heavy tungsten alloy because they weigh more than twice as much as steel. Tungsten alloys with high specific gravity are usually refractory metals containing tungsten nickel iron, tungsten nickel copper or tungsten nickel copper iron complexes. Some tungsten alloys have been added with rare earth and / or other metals such as cobalt, molybdenum and chromium. Heavy tungsten alloy has a high melting point, twice the density of steel and more than 50% heavier than lead.
Rivet is a permanent mechanical fastener. Before installation, it consists of a smooth cylindrical shaft with a head at one end. The end opposite the head is called the stag's tail. During installation, the rivet shall be placed in the drilling or pre drilling. Then the tail is "flipped" (i.e. deformed) to expand it to 1.5 times the original shaft diameter, and the rivet is fixed in place. In order to distinguish the two ends of the rivet, the original head is called the factory head, and the deformed end is called the shop head or the stag tail. Tungsten rivet reaction block is widely used in rivet gun.
Because there is a head at both ends of the installed tungsten rivet reaction block, it can support the tension load (load parallel to the shaft axis); However, it is more capable of supporting shear loads (loads perpendicular to the axis of the shaft). Bolts and screws are more suitable for tension applications.

The fasteners used in traditional wooden ships, such as copper nails and fastening bolts, are based on the principle of rivets, but tungsten rivet reaction blocks have been used long before the invention of rivets. People remember that they are usually classified as nails and bolts.
