碳化鎢/鎢鋼/Tungsten Carbide
碳化鎢，俗稱:鎢鋼，英文是 Tungsten Carbide ，也常被簡稱為Carbide (實際上carbide是碳化物的統稱)。
當然除了碳跟鎢之外還加了鈷以及其他的合金材料以增加他的機械性能..鎢鋼的硬度很高，所以常用來做為切削刀具的材質。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。
鎢鋼一般是用粉末燒結的方式製成..將鎢粉末、碳黑粉末、用作結合劑的鈷金屬粉末以及其他合金粉末混合後，施以高壓，在高溫下燒結而成。碳化鎢的硬度極高，摩氏硬度為8.5～9，且熔點達到2870°C

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.
