Many necklaces, rings and other items appear to be made of solid gold, but these items may only be gold plated. Discoloration, density and magnetism all provide clues that an item could be plated.

Skin Discoloration
Skin discoloration occurs when friction builds between the skin and the jewelry item. Real gold should not cause this discoloration, but gold plating covering a base metal, such as copper or nickel, sometimes wears through, and the other, less expensive base metal could cause skin discoloration.

Item Discoloration
The gold plated item itself sometimes discolors. If the gold depositing is laid too thinly over the base metal, the plating becomes porous, allowing the base metal to migrate through the pores and create a discoloring compound on the plating's surface.

Density
Gold density averages about 19.3 grams/mL. If the density of the piece in question varies too greatly from this measurement, the gold may only be plating. Weigh the piece in question against a known gold piece, or measure the displacement of water when the piece is submerged.

Magnetism
Gold does not attract magnets. If the piece in question proves to be magnetic, gold plating might be covering a magnetic base metal.

Military tungsten alloy swaging rod is made of tungsten alloy alloy. Afrter being swaged, the ultimate tensile strength of tungsten alloy rod is increased. The tensile strength of military tungsten alloy swaging rod
can reach 1200MPa, or even 1400MPa. Military tungsten alloy swaging rod is widely used for AGM-169.

The AGM-169 Joint Common Missile (JCM) was a tactical air-to-surface missile developed by the Lockheed Martin corporation from the United States.

The missile was designed to replace the AGM-114 Hellfire and AGM-65 Maverick. Its seeker head used a combination of semi-active laser, millimeter wave, and IR guidance similar to that found on the FGM-148 Javelin anti-tank missile. This allows the missile to have a greater fire and forget capability and to operate off all current air platforms. The missile has longer range, a more potent warhead, and a "safing" system, allowing naval aircraft to return to ship without jettisoning the munitions.

Tungsten alloy swaging rod consists of W-Ni-Fe, W-Ni-Cu or W-Ni-Cu-Fe. Tungsten alloy swaging rod is made of tungsten alloy rod. After being swaged, the ultimate stensile strength can reach 1200 MPa or even 1400MPa. Tungsten alloy swaging rod is widely used in military industries. The warhead of FGM-172 SRAW adopted tungsten alloy swaging rod.

The FGM-172 SRAW (Short-Range Assault Weapon), also known as the Predator SRAW, is a lightweight, close range missile system produced by Lockheed Martin, developed by Lockheed Martin and Israel Military Industries. It is designed to complement the Javelin anti-tank missile. The Predator has a longer range and is more powerful than the AT4 that it is designed to replace, but has a shorter range than the Javelin.

By using tungsten alloy swaging rod, FGM-172 SRAW can penetrate armor easily to destroy armor vehicles or tanks.

can reach 1200MPa, or even 1400MPa. Military tungsten alloy swaging rod is widely used for AGM-124 Wasp.

The AGM-124 Wasp is a missile developed by the United States of America. The Wasp grew out of the 1975 WAAM (Wide-Area Anti-Armour Munitions) program initiated by the US Air Force in order to develop a series of new air-to-ground anti-armour weapons for close-support aircraft. The three-pronged program led to the CBU-92/B ERAM (Extended Range Anti-Armour Munition), the CBU-90/B ACM (Anti-Armour Cluster Munition), and the Wasp anti-armour missile. The Wasp is regarded as the most advanced of these weapons.

With high tensile strength and high hardness of military tungsten alloy swaging rod, AGM-124 Wasp can penetrate armor by using kinetic energy and destroy armor vehicles.
