Common Brass Alloys and Their Uses

Brass is widely known as one of the most versatile alloys, perfect for several engineering and decorative applications. The pure copper+zinc alloy called “brass” has three types based on different crystal structures, as discussed in a previous post. But the versatility of brass is largely due to the myriad of possible combinations with other metals that change its characteristics based on what you need from it — the brass alloys. A few characteristics that can be manipulated by adding small percentages of other metals to brass are: Softness; Malleability; Hardness; Color; Resistance to corrosion; Stability. Below we’ll present some examples of brass alloys: Naval Brass Naval brass is a high-strength and especially corrosion-resistant brass alloy, which makes it, as its...

How to play Ship, Captain, and Crew

What you need: 5 dice and at least 2 people. In Ship, Captain, and Crew, players are pirates, assembling everything they need to plunder booty! The goal of the game is to win, and you win by having the most cargo after 5 rounds. Assembling the "ship" and "crew" Each turn consists of three rolls of the dice. The player must roll a 6, 5 and 4 in descending order.  For example: The first roll of the dice shows a 6 a 4 two 3's and a 1. The player banks the 6 but must reroll the 4 because there is no 5 yet.The second roll the player gets a 6 a 5 a 4 and a 1. The player...

The Different Types Of Brass

The most commonly used copper alloys in the industrial and commercial applications are so-called brass, traditionally applied to copper-zinc alloys. In this type of alloy, the zinc content varies between 5 (brass C 210) and 40% (brass C 280). The essential distinction between different types of brasses is determined by their crystal structures, because the combination of zinc and copper is represented by peritectic solidification, making them combine in different ways depending on the content ratios and temperatures. Here are the three different types of crystal structures that can be formed as a result of these factors: Alpha Brasses This is still a monophasic alloy, but already has very different characteristics from the red brass, starting with its yellowish coloration....
