In the Bronze Age, that is, in the late Neolithic Age, it was found that copper became a bronze alloy with high hardness and low melting point after adding lead and tin. It is very suitable as a good material for making weapons. It replaced the stone weapon. In addition, according to Kao Gong Ji's records, during the Warring States period, people had completely mastered the bronze smelting technology.

When smelting bronze, people can already adjust the proportion of bronze, lead and tin according to the different uses of the tools to be cast. It has been mentioned: "Gold has six qi: six points of its gold and one point of its tin bureau, which is called the qi of Zhong Ding; Jin Xi is divided into five parts, which is called axe; Three points of gold, three points of tin, combined into one, called Qi Dajian ... "All show that people's technology in bronze smelting was complete at that time.

Moreover, the casting skills mentioned in the book are also correct under the verification of modern science. Among all weapons, bronze is often the most intact after being unearthed, because an oxide layer will be formed on the surface of bronze after oxidation, which is very effective for the protection of weapons.

Bronze is brittle and hard. It's easy to cut, but hard to chop. From the unearthed artifacts, we can find that most of them are single-edged and single-edged. It is not difficult to see that the role of bronze blade as a daily appliance at that time was often greater than that as a weapon. The real weapons of war are those long bronze swords, and the early bronze swords had a good image in Shang Dynasty.

The initial length is only about 10 cm. Double blade. After a period of time, the length began to increase to about 40 cm. In order to take advantage, the hilt is wrapped with rough things such as silk and hemp. Later, as a formal weapon, as the main combat force on the battlefield. Finally, the length of the sword can be smelted to 50-60 cm.

During the Spring and Autumn Period, wuyue and China were famous for casting swords, and wuyue weapons unearthed in China can well prove this point. Their smelting technology is exquisite, and the magnificent craftsmanship can be seen from the unearthed swords. Swords generally have exquisite and mysterious textures, and the hardness of swords is extremely high. To this day, they are still cold and ready to fight.

At this time, the smelting technology of steel has also entered the historical stage, perhaps because smelting and casting have brought too much experience to the construction of ironware. Perhaps the creation of the two is the same.

In this era of China, steelmaking technology is a big step ahead of the world. No matter on TV or TV series, many famous swords were made in this era, and countless words also recorded the sharp and beautiful lines of swords at that time.

When we arrived in the state of Qin, we found in the unearthed cultural relics that bronze and iron weapons were used at that time. This sword is long and narrow. After careful polishing, there is a layer of black oxide to prevent decay. Compared with steel, bronze is more fragile, so its length is limited. The bronze sword of Qin dynasty is as hard as carbon steel, which also makes it

Future generations are amazed. When steel weapons officially appeared in the army, because of its strength and toughness obviously superior to bronze, the army began to use them in large quantities. By the end of the Western Han Dynasty, steel weapons had completely replaced bronze weapons.
