Weight of Brass Rounds

The Weight of Brass Rounds calculator computes the average weight of brass round bars based on the number and dimensions of the bars, and an average density of 8600 kg/m³ for brass bars.

INSTRUCTIONS: Enter the following:

• (n) Number of Round Rods
• (L) Length of Rounds
• (D) Diameter of Rounds
• (ρ) Density of Metal (Default: 8,600 kg/m³ for brass)

Weight of Brass Rounds (M): The function returns the weight in pounds. However this can be automatically converted to compatible units via the pull-down menu. 

The Math / Science

Brass is a soft, ductile metal with an excellent machinability rating. Brass is often used for projects that require strength, corrosion resistance, electrical conductivity, and non-sparking characteristics. It is commonly used for decorative purposes because shiny gold-like color and easy polishing.

The formula for the weight of metal bars is as follows:

         M = ρ • n • π • (D/2)² • L

where:

• M is the mass or weight of metal bars
• ρ is the density of the metal
• n is the number of bars
• D is the diameter of the bars
• L is the length of the bars

Application

Brass rods are versatile metal rods made from an alloy of copper and zinc. They’re commonly used in various industries because of their strength, corrosion resistance, machinability, and attractive gold-like appearance.

Common Uses of Brass Rods:

1. Manufacturing Components:
   • Gears, bearings, valves, and fittings, especially where corrosion resistance is important (e.g., plumbing, marine applications).
   • Electrical connectors and terminals due to brass’s excellent conductivity.
2. Decorative Purposes:
   • Handrails, curtain rods, light fixtures, and other ornamental items due to their shiny, gold-like appearance.
3. Machining and Fabrication:
   • Easy to machine and cut, making them suitable for precision parts and custom pieces.
4. Welding and Brazing:
   • Often used as filler material in brazing because of its lower melting point and compatibility with various metals.
5. Musical Instruments:
   • Parts of instruments like trumpets and saxophones, as brass produces a desirable acoustic quality.
6. Model Making and DIY Projects:
   • Ideal for hobbyists building small-scale models or custom tools.
7. Architectural Elements:
   • Decorative trims, brackets, and other fixtures where appearance and durability are desired.

The most common diameters of brass rods are typically measured in inches (for the U.S.) or millimeters (internationally). They are usually available in round, square, or hexagonal shapes.  This calculator computes the mass and weight for ROUND rods.

Most Common Diameters of Brass Rods:

Small Sizes (For Precision Work, Jewelry, Model Making):

• 1/16" (1.6 mm)
• 3/32" (2.4 mm)
• 1/8" (3.2 mm)
• 3/16" (4.8 mm)
• 1/4" (6.4 mm)

Medium Sizes (For General Fabrication, Machining, Hardware):

• 5/16" (7.9 mm)
• 3/8" (9.5 mm)
• 1/2" (12.7 mm)
• 5/8" (15.9 mm)
• 3/4" (19.1 mm)

Large Sizes (For Structural Components, Heavy-Duty Applications):

• 1" (25.4 mm)
• 1-1/4" (31.8 mm)
• 1-1/2" (38.1 mm)
• 2" (50.8 mm)
• 3" (76.2 mm)

Brass rods are often sold in standard lengths (e.g., 3 feet, 6 feet, 12 feet) but can also be cut to size.

Welding Calculators:
