Cycad, also known as South American sandalwood. The texture is straight, bright and delicate. More rare is that hematite contains a lot of metal minerals, so the texture is very hard and tough steel, so it got the "South American Golden Sandalwood" metaphor. Because hematoxylin production is not large, it is difficult to find its trace in the wood market. Household equipment made of total hematoxylin is even less. Cycas sinensis is over hundreds of years old, and its species is **. It has iron content, high tissue density, toughness, moisture resistance, non-shrinkage and non-expansion. It is suitable for the climate of all parts of China. It is the most stable and less flexible material in all light-colored floors at present. Wood tissue fine, soft vision, suitable for all seasons. The texture is intricate, the fibers are cohesive and have a halo, which will not crack and is full of aesthetic feeling.
According to documents and herbal reports from Loreto, Madre de Dios and San Martin provinces, the species is distributed at altitudes of 0-1000 meters. It is very abundant in the central part of the Amazon region and in the southern part of the Peruvian Amazon region.
Tree height is 30 meters or higher, trunk cylindrical, base exserted roots thin and protruding. The crown is umbrella-shaped and unfolds at a third of the tree's height. Leaves are not dense, ** layer branches yellow-green. The bark surface is slightly smooth and has a light particulate protuberance. The dead bark falls off in large irregular layers, like a maze, leaving only traces of a thin layer of cork. Scrape off this layer of cork and you can see that it's yellow-green. The main part of bark is divided into two layers: the outer layer is layered, compact, pink, some areas are light orange, the inner layer is layered, multi-fiber, dense.
The sapwood of newly cut down trees is creamy yellow, and the heartwood is bright yellow. The color difference between sapwood and heartwood is obvious. After air drying, the sapwood turned yellow HUE 8/62.5Y and the heartwood turned light yellowish brown HUE 6/8 10YR.
The wood weight, linear shrinkage and volume shrinkage of hematoxylin are moderate and stable. Medium to high mechanical resistance. Because the wood contains silica, it needs to be sawn with star tools. In the drying process, the wood is stable and the risk of warping is small. It is resistant to biological invasion and does not need antiseptic treatment.
The wood is hard and local people use it to make canoes and ships. It is also used to manufacture vehicles, heavy buildings, supporting buildings, poles, columns, railway sleepers, floor tiles, decorative panels, doors and window frames.
