STB 碳化鎢條
"STB"：一般理解為一種稱號或等級，通常指標準的矩形截面硬質合金產品。在英文中，常解釋為 "Standard Tool Blank" 的縮寫。
「條狀」：指形狀，即長方形的條狀材料。
當然，您還是可以自訂不同的尺寸，這對我們來說很容易做到。
使用粉末冶金製程生產的碳化鎢條具有超越許多其他材料的獨特組合特性。碳化鎢的固有硬度接近鑽石，即使在高應力和高溫下，也能形成鋒利的切削刃。鈷粘合劑提供了必要的韌性，防止原本脆性的碳化物在撞擊下斷裂。
STB 碳化鎢帶材的多功能性反映在其廣泛的應用上。在木工和金屬加工產業中，它們被用於切削工具刀片、鋸齒和刨刀，因為它們能夠長時間提供乾淨、精確的切削。它們的耐磨性和耐腐蝕性也使它們成為製造耐磨零件的理想材料，例如各種機械中使用的噴嘴、導軌和板。
STB 碳化鎢帶材有多種等級，每種等級的碳化鎢與鈷的比例和晶粒大小各不相同。這使得它們能針對特定應用量身打造屬性。例如，鈷含量越高，韌性越強，更適合高衝擊應用。相反，較低的鈷含量和較細的晶粒則可增加硬度和耐磨性，使其成為精密切削工具的理想選擇。製造過程包括高溫壓制和燒結，以確保最終產品致密均勻，性能可靠。
