Why is clam wood called the steel tree? What is the origin?

Clam wood is called the steel tree, this is mainly because its material is very dense, the density is greater than the density of water, it sinks when it enters the water, it is still very hard, even harder than steel, so it is also called the steel tree, because it is as hard as steel is not easy to cutPeople also have special tools for cutting clam wood, which must be used to cut it, but now the state has listed it as a second-class protected plant, and this kind of tree can no longer be cut down.

Clam wood is also a special shipbuilding material, and some people have tried to nail clam wood, but they did not nail it in, and the clam wood is too hard, and this is mainly because it likes to grow on rocks, and its roots absorb a lot of rock minerals, so it makes its entire trunk particularly hard. This kind of tree is mainly distributed in the rainforest of Guangxi and Yunnan in China, and the growth rate of this kind of tree is also very slow, and a clam that can be used as a material needs to grow for more than 100 years. Clam wood is also strange, the longer it grows, the harder it becomes.

People generally use this kind of tree to make cutting boards, because it is very hard, so that no matter what is cut on the cutting board, this cutting board will not break, and it is very durable, and some people say that whoever has such a cutting board will be envious of the neighbors next door. But now that this tree has become a protected plant, it can no longer be used as a cutting board, and everyone who bought it in the past will be very envious of others.

The texture of this tree is also very beautiful, and it can be stored for a long time, because it is very resistant to corruption and water, and the insect resistance is also very goodBecause its wood is very hard and heavy, there are a lot of people who use it to make mechanical skids, and there are also many rich people who use this wood to make some high-end furniture, due to people's overexploitation, there are not many such trees at present.

Because the wood of the clam itself is so hard that even nails can't be driven into it, it is called a steel tree. The reason why the clam wood is so hard is related to the environment in which it grows, the clam grows in limestone areas and absorbs a lot of calcium, resulting in a hard wood.

This precious tree is about 20 meters high, with a trunk diameter of about 70 centimeters, and a lifespan of about 300-350 years. The bark is dark red or almost black with white spots on top. The leaves are oval in shape.

It is not widely produced, mainly in the southern part of North Korea and the border areas between North Korea and China, and there are also some along the southern coast of Russia.

Indian steel wood is three times harder than oak and twice as hard as ordinary steel, making it the hardest wood in the world, and people use it as a substitute for metal. The former Soviet Union used Indian steel and wood to make rolling balls and bearings, which were used in speedboats. Indian steel wood also has some wonderful properties, because it is extremely dense in texture, so it sinks as soon as it is placed in the water; Even if you soak it in water for a long time, the inside of it will remain dry.

Indian steel wood is propagated by seeds, and is a birch family, a birch plant. Deciduous tree with unisexual flowers, monoecious, inflorescences, nuts, membranous wings on both sides. Seeds are spread by the wind.

Light-loving, hardy, drought-tolerant and barren.

Because the value of the steel tree is very high, the material is harder than steel, but now it has been cut down in excess of it, so it has been listed as a national second-class protected plant.

Because clam wood is heavy and difficult to cut, it also makes a metal-like sound when struck, and it mainly grows in limestone areas and absorbs a lot of minerals and calcium.

There is a difference between clam wood and ironwood.

Clam wood, also known as fire wood, linden tree family tiliaceae, evergreen large tree, endangered species. It is distributed in the tropical limestone mountain monsoon forests of Guangxi and Yunnan at an altitude of 700 to 900 meters. It blooms in March and ripens in June, with fruiting intervals of 2 to 3 years.

It is one of the founding species of the native limestone seasonal rainforest in the northern tropics, and is an endemic plant of tropical limestone, which has important research value. Its wood is strong and has excellent mechanical properties, and it is listed as a national first-class precious tree species and a national second-class protected plant. Chinese scientific name:

Clam Latin scientific name: excetrodendronhsiemvu (chunethow) alias: firewood world:

Plant Family: Tiliaceae Distribution area: Guangxi, Yunnan (Western Domain).

"Ironwood" is a synonym for "healed wood".

It belongs to the family Zygophyliaceae. 80% of the tree is used for the shipbuilding industry. At present, foreign production is getting smaller and smaller.

It is regarded as a rare and important shipbuilding material in various countries. It is said that in 100 years, it can only reach a diameter of 10 inches in the bust. Therefore, the local Latin people call it the "wood of life".

However, the scope of use of ironwood is expanding, such as wear-resistant parts in the machinery industry, bearing materials in chemical reactors, and mud pumps and rollers in the paper industry. As a result, demand has increased and demand has become more unbalanced.

Why is it that the beautifully packaged ironwood cutting board tree heart bought in the supermarket or on the market is easy to fade, fall off and damage in the middle of the first few tens of yuan in less than a month or two or a year?

Answer: There is a trademark, there is a brand, it seems to be ideal, but for the ironwood cutting board, the brand, the packaged cutting board is often a symbol of inferior ironwood cutting board, the local people will never buy, because the brand cutting board has been industrially beautified, and the trademark office will often cover the defects, there are patches and other bad defects, not easy to check, and even most of them are directly fakes, this.
