Abstract

The present invention relates to a kind of low-cobalt glass sealing fernico. Its cobalt content is 8-12%, and it also contains a small quantity of niobium. As compared with traditional fernico, the dose of expensive metal cobalt is reduced by about 50%, so its raw material cost is reduced by above 30%. Besides, said invention possesses good sealing property between said invented product and hard glass at 20-450 deg.C.

Description

Low cobalt glass sealed iron-nickel-cobalt alloy
The present invention relates to a kind of alloys with controlled expansion, specifically a kind of can with glass-sealed metallic substance.
Such as many electronic products such as glass switch pipe, electron tubes, all need to use can with the special metal material of hard glass sealing-in.This metallic substance will have the coefficient of expansion identical or close with hard glass in specific temperature range, can obtain ideal sealing-in effect.So far, being used for 20 ℃~450 ℃ traditional metallic substance is fernicos, this alloy is with iron, nickel, cobalt metal and a small amount of manganese, silicon, process by batching, melting, cast, forging, hot rolling, operation such as cold rolling, the weight percent of metallic element is in the alloy: Co accounts for 16.8~17.8, and Ni accounts for 28.5~29.5, and manganese accounts for below 0.5, Si accounts for below 0.3, and all the other mainly are Fe.This alloy is owing to containing more expensive cobalt metal (the cobalt valency is about seven times of nickel valency approximately), so the cost of material is very high.
The objective of the invention is: a kind of cheap, well behaved novel expansion alloy material is provided.
The present invention is achieved in that in the alloy made from iron, nickel, cobalt and a small amount of manganese, silicon, reduce the content of cobalt, the content that the while is suitably improved nickel, and a small amount of other metallic element of increase, the weight percent of each element in alloy is: Co accounts for 8~12, Ni accounts for 28~35, Mn accounts for below 1.0, and Si accounts for 0.1~0.8.And containing 0.1~2.0 Nb, all the other are mainly Fe.0.1~2.0 Cu can also be arranged in the alloy.Trace element Nb plays crystal grain thinning in alloy, improve the processing characteristics of alloy; A small amount of Cu can improve and hard glass between the performance of matched seal.This alloy adopts conventional fernico production technique, makes through batching, melting, cast, forging, hot rolling, operation such as cold rolling.
The present invention is owing to greatly reduce expensive cobalt contents, thereby the production cost that has reduced material is more than 30%.The sealing property of this alloy and hard glass is good, and stress of sealing be lower than that tradition uses contain the higher fernico of Co.
Be two embodiment of the present invention below.
Embodiment 1:
Undertaken by following step: 1. prepare burden, various metal ratio are Fe: Ni: Co=56: 34: 10, add the Mn of total amount 0.3% and 0.1% Si, and add 0.1% Nb; 2. vacuum melting; 3. cast.1540 ± 10 ℃ of teeming temperatures; 4. forge, forge 1150~1180 ℃ of beginning temperature, final forging temperature is greater than 900 ℃; 5. hot rolling, temperature are 1130 ± 20 ℃; 6. thermal treatment. temperature is 900 ± 20 ℃, is incubated 40 minutes.The degree of major metal element: Co is 10.81 in this alloy, and Ni is 33.98, and Nb is 0.10, and Si is 0.073, and Mn is 0.21, and Fe is surplus, this composition alloy: at 20~400 ℃ the coefficients of expansion is 4.7 * 10 -6/ ℃; At 20~450 ℃ the coefficients of expansion is 5.7 * 10 -6/ ℃.
Embodiment 2:
Ratio of components is Fe: Ni: Co=57: 34: 9, adding accounted for the Mn of total amount 0.5% and 0.3% Si, and added the Nb of gross weight 0.1%, and other step is with embodiment 1.The chemical ingredients of making alloy is as follows: Co is 8.78, and Ni is 34.52, and Nb is 0.1, and Si is 0.25, and Mn is 0.44, and surplus is Fe.The coefficient of expansion of this alloy is as follows:
In the time of 20~400 ℃, the coefficient of expansion is: 5.3 * 10 -6/ ℃;
In the time of 20~450 ℃, the coefficient of expansion is: 6.3 * 10 -6/ ℃.

Claims (2)

1, low cobalt glass sealed iron-nickel-cobalt alloy, with metallic iron, nickel, cobalt and a small amount of manganese, silicon, process by batching, melting, cast, forging, hot rolling, operation such as cold rolling, it is characterized in that, the weight ratio that contains each major metal element in the alloy is: Co accounts for 8~12, Ni accounts for 28~35, and contains 0.1~2.0 Nb, and all the other are mainly Fe.
2, according to the said low cobalt glass sealed iron-nickel-cobalt alloy of claim 1, it is characterized in that, also contain 0.1~2.0 Cu.
