Is bronze hard to machine?

Machinability. PB1 Phosphor bronze has very good machining qualities and is free cutting but very tough; the use of tipped tools is recommended. Bronze gets hot when drilling and turning, therefore, the use of a coolant is recommended.

Is aluminum bronze easy to machine?

Main Attributes of Aluminium Bronze: High hardness. Excellent corrosion resistance – particularly in marine environments. Excellent shock & wear resistance. Can be difficult to machine.

What is C630 bronze?

aluminum nickel bronze
C630 is commonly referred to as aluminum nickel bronze because it is an alloy with inherent bronze properties. These types of metals are highly regarded for their strength and corrosion resistance when compared to other bronze alloys.

How strong is aluminum bronze?

Mechanical Properties

Yield Strength @ .5% ext under load min 32 ksi 221 MPa
Elongation in 2 in. or 50 mm min, % 12
Brinell Hardness 170 typical Bhn (3000kg)

Is bronze or brass more expensive?

Bronze is usually more expensive than brass, partly due to the processes required to manufacture bronze.

What is harder brass or bronze?

Regardless of the elemental addition, bronze demonstrates greater hardness than pure copper. On the other hand, brass mainly contains copper and zinc, the latter of which allows for enhanced strength and ductility….The Differences Between Bronze and Brass.

Bronze Brass
Harder, more brittle Greater malleability

What is phosphor bronze used for?

The phosphor bronzes have superb spring qualities, high fatigue resistance, excellent formability and solderability, and high corrosion resistance. They are primarily used for electrical products, other uses include corrosion resistant bellows, diaphragms, and spring washers.

What is nickel aluminum bronze?

Nickel-aluminum bronze (NAB) is a metallic alloy that is widely used for ship valves and propellers, among other marine applications.

Is steel aluminum harder than bronze?

Tensile Strength Some aluminum bronzes exhibit strengths comparable to low alloy steels and many are stronger than most stainless steels. Furthermore, the alloys retain a substantial proportion of their strength at elevated temperature, and at low temperatures, they gain strength slightly while retaining ductility.

Does bronze last forever?

Primitive bronze artifacts have been found dating back to early Greek and Roman cultures thousands of years ago. It is thought that today’s bronze memorials, which are much better quality, will last virtually forever. Even though it lasts a long time, bronze can be a bit expensive.

Which is the best bronze alloy for free machining?

C932, aka SAE 660 is pretty much a free-machining alloy due to the high lead content. C95400 (C954, 9C, CuAl11Fe4),is a high strength “bronze” that machines more like a stainless steel than a bronze/brass, it is also very abrasive.

What kind of metal is c 630 nickel?

C 630 Nickel Aluminum Bronze is an extruded aluminum bronze that contains nickel, and is alloyed for exceptional strength and toughness. It’s used where higher mechanical properties are required. It’s used in equipment for the energy markets, in aircraft, marine and a host of other industrial applications.

When to use lubrication when machining nickel aluminum bronze?

Lubrication is recommended when machining Nickel Aluminum Bronze, particularly where close tolerances are required. Like other copper based alloys, heat generation caused by the machining of the metal can cause expansion and when the part cools can result in contraction which will take the part out of tolerance.

What is the color code for c 630?

630 Color Code. C 630 Nickel Aluminum Bronze is an extruded aluminum bronze that contains nickel, and is alloyed for exceptional strength and toughness.
