The 101 On Thermal Conductivity In Metal Alloys

Dave Olsen — Wed, 27 Sep 2023 19:31:36 +0000

One crucial property to understand in metalworking is thermal conductivity. The simplest definition of thermal conductivity is a material’s ability to transfer or conduct heat from one location to another efficiently. A more technical definition from Science Direct is, “Thermal conductivity can be defined as the rate at which heat is transferred by conduction through…

A Guide to Different Types of Bronze Alloys

Dave Olsen — Tue, 15 Aug 2023 18:58:40 +0000

Introduction Bronze is a copper-based alloy that has been valued throughout history for its versatility, durability, and attractive nature. Bronze is composed primarily of copper with various combinations of tin, zinc, lead, and aluminum. This combination also produces brass. Brass contains a larger amount of zinc than tin, while bronze contains larger amounts of tin…

What Is Pitting Resistance Equivalency Number (PREn)?

admin — Tue, 01 Dec 2020 20:47:32 +0000

The Pitting Resistance Equivalency Number (PREn) is an objective way to do an initial comparison of the relative resistance to corrosion of various metals. It is based on a calculation that considers the weight percentage of alloying elements. Pren Number Formula: PREn = % Cr + (3.3 x % Mo) + (30 x % N)…
