這種合金屬于精密合金，又稱可伐。它是鐵、鎳、鈷的合金，一般含鎳29%，鈷18%，其余是鐵。其膨脹系數(shù)由于鈷的加入而降低，與鉬及硬玻璃相近，適合于和硬玻璃作匹配封接。封接時表面生成有氧化鉆的氧化層，而氧化鈷極易溶于玻璃中而形成鼠灰色的封接面。當氧氣不足時，由于氧化層幾乎全部溶入玻璃而使封接面呈金屬本身的銀白色，雖不漏氣，但強度很差。氧化過度時，則因氧化層太厚而呈深灰色甚至黑色，易造成漏氣。<br /> 可伐的優(yōu)點是其膨脹系數(shù)隨溫度變化的曲線與鉬組玻璃的膨脹曲線幾乎重合，因此與鉬組玻璃封接時，其可靠性更高，這就使封接后的退火工藝較為簡單?？煞サ娜秉c是在變形加工時，它的結晶結構易于轉變(奧斯丁體轉變成馬丁體)而使性能變化，如電阻率增加。因此，可伐零件在進行這類加工后，必須進行退火處理。在封接前，可伐零件須在1000℃左右濕氫中的退火，既可應力，還可使表面脫碳，這就使可伐不致在今后封接加熱時，由于表面碳的氧化使封接處出現(xiàn)氣泡而降低了封接處的強度和造成慢性漏氣。另外，因可伐的電阻率高，如用作引線時，若考慮到過熱所引起的炸裂問題，一般要在可伐表面上鍍上一層高導電率的材料，如金、銀、銅．或做成大面積接觸?？煞サ某煞直壤苤匾駝t將影響封接面的應力。 <br /> 在電真空器件中，鐵鎳鉆封接合金廣泛地用來制造引出環(huán)、引出線和管殼等零件。</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212305239023.jpg" title="可伐合金毛細管原廠定做"><br></p><div id="8c5snjp" class="khcont2">可伐合金毛細管又稱定膨脹合金毛細管<br /> 膨脹合金毛細管的居里點約為230℃，低于這一溫度時合金是鐵磁性的，具有很低的膨脹系數(shù)，高于這一溫度時合金為無磁性的，膨脹系數(shù)增大。<br /> 膨脹合金毛細管是一種具有超低膨脹系數(shù)的特殊的低膨脹鐵鎳合金。其中對碳、錳成分的控制非常重要。冷變形能降低熱膨脹系數(shù)，在特定溫度范圍內的熱處理能使熱膨脹系數(shù)穩(wěn)定化。在室溫干燥空氣中膨脹合金具有抗腐蝕性。在其他惡劣環(huán)境中，如潮濕空氣中，有可能會發(fā)生腐蝕（生銹）。<br /> 膨脹合金毛細管在-250℃和+200℃之間具有極低的熱膨脹系數(shù)，很好的塑性和韌性。該合金主要用于制造在氣溫變化范圍內尺寸近似恒定的元件，廣泛用于無線電工業(yè)、精密儀器、儀表及其他工業(yè)。該合金是典型低膨脹合金。經(jīng)航空工廠長期使用，性能穩(wěn)定；使用中應嚴格控制熱處理工藝及加工工藝，以保證材料的穩(wěn)定性。<br /> 用途：主要用于電真空元器件如發(fā)射管、振蕩管、引燃管、磁控管、晶體管、密封插頭、繼電器、集成電路的引出線、底盤、外殼、支架等的玻璃封接。</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212305187631.jpg" title="可伐合金毛細管原廠定做"><br></p><p><img
