碳化鎢是一種由鎢和碳組成的化合物，化學式為WC，英文為Tungsten Carbide，也常被簡稱為Carbide（實際上carbide是碳化物的統稱）。碳化鎢的硬度極高，摩氏硬度為8.5～9，且熔點達到2870°C，電阻亦低，常被用做切削刀具材料（可切削不鏽鋼）、製造高硬度裝甲或穿甲彈彈芯，以及一些需要高硬度的運動器材零件，以及原子筆的筆尖圓珠等。頂針一般頂針是一種裁縫時戴於某個手指，用來保護手指的殼狀物。 最早的頂針由羅馬龐貝城出土，材質為青銅，製造時間為西元前79年。在今英國的St Albans也發現了羅馬的頂針，現保存於博物館。頂針的材料包括金屬、皮革、橡皮、木頭、玻璃或瓷。早期的頂針有時會以鯨骨、角、象牙製成，天然材質包括石材、貝等材質。使用鑽石、藍寶石或紅寶石的頂針則非常少見。我們的頂針是使用在晶圓製造方面，用於...
Our double point needles were the first carbon fiber knitting needles in the world ! They are not made of metal, wood, or plastic. What they are made of is a Carbon Fiber Composite - the same material used in the new Boeing 787 Dreamliner and the Blackbird Stealth Jet as well as sporting goods that demand strength in a lightweight material. With their nice pointy tips, we decided that the name Blackthorn DPNs described them perfectly.Read about us on Ravelry! This link will take you to our Blackthorn DPNs Group. The Group threads are packed with actual user reviews, pictures, comments and answers from myself and fellow knitters.These sets of 5 needles -- in eight sizes from US 0000 to 4 have the feel of bamboo (smooth but not slick) and feel warm to the touch. They are as strong as but more flexible than steel.We make our needles in the popular 6" length to accommodate most knitting styles and projects. Your order of Blackthorn DPNs will come in a re-useable clear plastic pillow box.
