\n Pirin\u00e7 olduk\u00e7a sert ve kolay i\u015flenebilen bir malzemedir. D\u00f6v\u00fclebilirli\u011fi bak\u0131r muhtevas\u0131na ba\u011fl\u0131d\u0131r. % 55’ten az bak\u0131r ihtiva eden beyaz pirin\u00e7ler kolay i\u015flenemez. Bunlar ancak toz haline getirilerek sert lehim i\u015flemlerinde kullan\u0131lma sahas\u0131 bulurlar. D\u00f6v\u00fclebilir pirin\u00e7ler ise genellikle % 62’nin \u00fczerinde bak\u0131r ihtiva eden ve so\u011fuk olarak i\u015flenebilen alfa pirin\u00e7leri ile daha az bak\u0131r ihtiva eden ve s\u0131cak i\u015flem gerektiren beta pirin\u00e7leridir. Alfa pirin\u00e7leri \u00fcst\u00fcn so\u011fuk i\u015flem \u00f6zelliklerine sahip olup c\u0131vata pim ve vida yap\u0131m\u0131nda yayg\u0131n olarak kullan\u0131l\u0131r. Beta pirin\u00e7leriyse daha az s\u00fcnek fakat daha dayan\u0131kl\u0131d\u0131r. Bunlar bilhassa musluk vanas\u0131 kap\u0131 ve pencere kolu ve baz\u0131 ba\u011flant\u0131 par\u00e7alar\u0131n\u0131n imalinde kullan\u0131l\u0131r.

Mesela al\u00fcminyumlu pirin\u00e7ler korozyona kar\u015f\u0131 dayan\u0131kl\u0131d\u0131r. Kur\u015funlu pirin\u00e7ler kolay i\u015flenir. Kalayl\u0131 pirin\u00e7ler ise deniz suyunun korozif etkisine kar\u015f\u0131 diren\u00e7lidir.
