Problems solved by technology

[0003] At present, the raw material used for copper wires for plastic pressure measuring sensitive components in my country is oxygen-free copper. The oxygen-free copper composition is copper content ≥ 99.99%, oxygen content ≤ 0.001%. The uniformity of the copper column, but the copper column prepared by the copper wire has the defect that the strength is soft. The so-called copper column rigidity refers to the post-compression height or deformation of the copper column under a certain static loading force value. The copper column The existence of toughness and softness directly affects the use of copper pillars in plastic pressure measuring instruments; and because the process of preparing copper wires from oxygen-free copper is harsh on the environment, the performance of copper wires produced varies greatly from batch to batch, resulting in The strength of copper pillars made of copper wire varies greatly from batch to batch

Description

technical field [0001] The invention relates to a copper wire for a plastic pressure measuring sensitive element. Background technique [0002] The copper wire for the plastic pressure sensitive element is a raw material for preparing the copper column of the plastic pressure sensitive element. The copper pillar of the sensitive element is made of copper wire through certain mechanical processing, so the mechanical strength, uniformity, stability and other indicators of the copper wire directly affect the performance indicators of the sturdiness, uniformity, and surface strength of the copper pillar, as well as the performance index of the copper pillar. Column batch-to-batch stability. Therefore, the performance of the copper wire affects the accuracy of the copper column of the plastic pressure sensor to test the pressure in the gunpowder chamber. [0003] At present, the raw material used for copper wires for plastic pressure measuring sensitive components in my country...
