Compatible with lead free soldering process.

兼容无铅焊接工艺。

In this paper both lead borate sealing glasses and lead free phosphate sealing glasses are studied.

本文研究了含铅的硼酸盐封接玻璃和无铅磷酸盐封接玻璃。

The primary object of the present invention is to provide a substantially lead free alloy that is press quenchable.

本发明的主要目的是提供可模压淬火的基本不含铅的合金。

In the course of the lead free reflow soldering, lead and lead free of reflow soldering affect the quality of product.

在再流焊无铅化过程中，再流焊的有铅要素与无铅要素的兼容性直接影响产品质量。

In addition, the lead free gasoline is being used in the engine, so vavle seat insert (VSI) must be made by scpecial materials.

燃料改用无铅汽油以后，阀座部分必须用特种材料制造的镶圈来补强，这种镶圈就是通常所谓的阀座圈。
