2.定膨脹合金或稱封接合金，一般在-70～500℃溫度范圍內(nèi)具有恒定的較低的或中等程度的膨脹系數(shù)。<br /> 3.高膨脹合金，一般指在室溫至100℃溫度范圍內(nèi)具有很大的膨脹系數(shù)的膨脹合金。<br /> 低膨脹合（因瓦合金）主要用于精密儀器儀表，光學(xué)儀器中的元件：精密天平的元件，長度標(biāo)尺，大地測量基線尺，各種諧振腔，微波通訊的波導(dǎo)管，標(biāo)準(zhǔn)頻率發(fā)生器和熱雙金屬的被動層等等。<br /> 封接合金在一定的溫度范圍內(nèi)，具有與玻璃或陶瓷等被封接材料相接近的膨脹系數(shù)從而可以達(dá)到匹配封接的效果，因此也稱之為封接合金，它廣泛用于電子管，晶體管和集成電路中作引線和結(jié)構(gòu)材料封接合金，<br /> 也稱可伐合金在較寬的溫度范圍(-80—450℃)內(nèi)膨脹系數(shù)與硬玻璃的膨脹系數(shù)相近，在電真空工業(yè)中，用來與硬玻璃封接制造高可伐合金（KOVAR）系列執(zhí)行標(biāo)準(zhǔn)：YB/T5231-1993（4J29） YB/T5235-1993（4J42 4J45 4J50）<br /> <br /></div><p><img

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(dāng)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(qiáng)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(diǎn)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。可伐的缺點(diǎn)是在變形加工時，它的結(jié)晶結(jié)構(gòu)易于轉(zhuǎn)變(奧斯丁體轉(zhuǎn)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(jìn)行這類加工后，必須進(jìn)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(yīng)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(qiáng)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(dǎo)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?，否則將影響封接面的應(yīng)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/86/1136/202402212305130185.jpg" title="可伐合金毛細(xì)管企業(yè)-實(shí)力雄厚"><br></p><p><img
