SUMMARY

The discussion focuses on identifying the type of brass most susceptible to corrosion for experimental purposes. The user seeks a brass alloy that will yield visible corrosion results when exposed to common bases, acids, and salts. It is established that dezincification is a critical factor in determining corrosion susceptibility, and specific brass types should be researched for their properties related to this phenomenon. The user has consulted brass suppliers but received limited scientific guidance.

PREREQUISITES
  • Understanding of brass alloys, specifically the composition of copper and zinc.
  • Knowledge of corrosion processes, particularly dezincification.
  • Familiarity with common corrosive agents such as acids, bases, and salts.
  • Basic experimental design principles for conducting corrosion tests.
NEXT STEPS
  • Research specific brass alloys known for high susceptibility to dezincification.
  • Investigate the effects of different corrosive agents on brass, focusing on common bases and acids.
  • Explore corrosion testing methodologies to quantify results effectively.
  • Review case studies or experiments that document corrosion rates of various brass types.
USEFUL FOR

This discussion is beneficial for materials scientists, chemistry students, and anyone conducting experiments related to metal corrosion, particularly those focusing on brass alloys.

Homework Statement


I have been given the task to corrode brass with common base, acid and salt. I understand that it is an alloy of copper and zinc and is actually designed not to rust. Before I begin the experiment, I am looking for the best TYPE of brass to use in this experiment. Given that there appears to be hundreds of different types of brass with different properties, which type will give me the best chance for visible results?


Homework Equations


Brass is an alloy of copper and zinc


The Attempt at a Solution


I have looked all over the internet... and have contacted several "brass wholesale suppliers" who have simply stated that they are not "scientists."

Include "dezincification" in your search for brass. You want a brass that is http://corrosion-doctors.org/MatSelect/corrbrass.htm"
