LG2 Bronze (Leaded Gunmetal)

Overview

LG2 Bronze is one of the most commonly used grades of bronze in New Zealand industry.

It has medium strength, excellent machining properties, and is suitable for bearings, gears and other components used in relatively light duty applications. Although LG2 is often referred to as phosphor bronze, it is in fact a leaded gunmetal. Only the “PB” group of bronzes (PB1, PB2 etc) can truly be called phosphor bronze.

All Milsons LG2 bronze is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength is superior to sand-casting methods. This also means that the material has a fine grain structure and is free from porosity.

Machining Allowances

All Kormax LG2 Bronze bar has machining allowances added to the sizes quoted. To use 4-1/2” x 2-1/2” hollow bar as an example, this material would measure approximately 4.570” OD x 2.440” ID as supplied (see table below). Therefore this allows finished components measuring 4-1/2” OD x 2-1/2” ID to be easily manufactured from 4-1/2” x 2-1/2” hollow bar.

Machining allowances are as follows:

Outside Diameter Inside Diameter
Size Range Allowance Size Range Allowance
up to 3-3/4” +0.040” up to 3-3/4” -0.060”
4” to 5” +0.070” 4” to 5” -0.090”
5-1/4” to 6” +0.094” 5-1/4” to 6” -0.108”
6-1/4” to 18” +0.109” 6-1/4” to 18” -0.120”
