F-15）用途:用于制作與硬玻璃匹配封接的鐵鎳鈷合金帶材,棒材,板材,管材。適用于發(fā)射管、振蕩管、引燃管、晶體管以及管封插頭度、繼電器外殼等電真空器件。在20℃-450℃溫度范圍內(nèi)具有一定的線膨脹系回?cái)?shù)，能與硬玻璃進(jìn)行匹配牢固封接。可伐合金（也稱Kovar合金）主要適用于電器元件與硬玻璃、軟玻璃、陶瓷匹配封接的玻封合金，其狀態(tài)有硬態(tài)和軟態(tài)兩種．規(guī)格為0.25mm以上．另可按客戶要求訂做符合其規(guī)格的絲材，棒材，管材，帶材，板材。價(jià)格電議。特點(diǎn)與用途：在20°C-450°C的范圍內(nèi)有與硬玻璃相連接的膨脹系數(shù)，和較高的居里點(diǎn)以及良好的低溫穩(wěn)定性，合金的氧化膜致密，容易焊接和熔接，有良好可塑性，可切削加工，廣泛用于制作電真空元件，發(fā)射管，顯像管，開(kāi)關(guān)管，晶體管以及密封插頭和繼電器外殼等。<br /> KOVAR（可伐）ASTM F15合金是常用的高完整性的控制膨脹合金，膨脹系數(shù)與陶瓷玻璃相近，適用于陶瓷或玻璃與金屬的封接，主要應(yīng)用于電路外殼，光電子外殼，電子管，晶振，CRT電子槍零件等領(lǐng)域。</div><p><img

可伐合金常見(jiàn)類型：玻璃封接用鉻鐵合金、鐵鎳鈷玻璃封接合金、鐵鎳鈷陶瓷封接合金等。<br /> 鐵鎳鈷陶瓷封接合金<br /> 這種合金屬于精密合金，也是鐵、鎳、鈷的合金，又稱為陶瓷可伐。在-60-600℃時(shí)它的膨脹系數(shù)與95%氧化鋁陶瓷相近，常用來(lái)和陶瓷作匹配封接。在金屬陶瓷發(fā)射管、行波管、速調(diào)管等器件和真空電容器中，鐵鎳鉆陶瓷封接合金廣泛地用來(lái)制作引出線、引出環(huán)、管殼等零件。<br /> 鐵鎳鈷玻璃封接合金<br /> 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(shí)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。<br /> 玻璃封接用鉻鐵合金<br /> 和玻璃封接用的鉻鐵合金是含鉻28%的鉻鐵合金，又稱做高鉻鋼或28號(hào)膨脹合金。合金中由于加入了鉻，使膨脹系數(shù)降低，因此可與軟玻璃進(jìn)行匹配封接。含鉻量高的鉻鐵合金，一般在室溫至熔點(diǎn)溫度的全部范圍內(nèi)將是鐵氧體的狀態(tài)，所以也稱做鐵氧體的鉻鐵合金。 </p></div><p><img
