Copper and aluminum weight calculation method

Copper rod
W = 0.00698 × square of diameter

Brass rod
W = 0.00668 × square of diameter

Aluminum rod
W = 0.0022 × square of diameter

Square copper rod
W = 0.0089 × square of the side width

Square brass rod
W = 0.0085 × square of the side width

Hexagonal copper rod
W = 0.0077 × square of the distance of the opposite side

Hexagonal brass rod
W = 0.00736 × square of the distance of the opposite side

Copper plate
W = 0.0089 × thickness × width

Brass plate
W = 0.0085 × thickness × width

Aluminum plate (pure aluminum)
W = 0.00271 × thickness × width

Patterned aluminum plate (pure aluminum)
W=0.00271×thickness×width×length+(width×length×0.6)

Copper tube
W = 0.028 × wall thickness × (outer diameter - wall thickness)

Brass tube
W=0.0267×wall thickness×(outer diameter-wall thickness)

Aluminum tube
W=0.00879×wall thickness×(outer diameter-wall thickness)

Copper row
W = 0.0089 × width × thickness

Aluminum row
W = 0.0027 × width × thickness

Note: The unit of W is kilograms/meter, and the other units are millimeters.

Tang Sword

The Tang Sword, also known as the Tang Dao, is a traditional Chinese weapon that originated during the Tang Dynasty (618-907 AD). It is a single-edged straight sword with a slightly curved blade, measuring around 70-100 centimeters in length.

The Tang Sword is renowned for its excellent craftsmanship and superior cutting ability. It is often praised for its balance and versatility, making it suitable for both slashing and thrusting techniques. The blade is typically made of high-quality carbon steel, which provides durability and sharpness.

The hilt of the Tang Sword is usually made of hardwood, wrapped in leather or silk for a comfortable grip. It features a circular or rectangular guard, known as a tsuba, to protect the hand during combat. The pommel, often adorned with decorative elements, adds balance to the sword.

In addition to its practical use in combat, the Tang Sword is also considered a work of art. Its elegant design and intricate engravings make it a prized possession for collectors and enthusiasts. The craftsmanship and symbolism behind the Tang Sword reflect the rich heritage of Chinese martial arts and the Tang Dynasty.
