The rods may be rifle drilled or they may have cast passages for transferring oil from the wrist pin to the crank pin. A connecting rod with a tension load is made of forged steel, cast steel, or fabricated steel. Rods with a compression loading are cast nodular steel or aluminum alloy.

How are engine rods made?
The manufacturing of connecting rods varies, depending on whether they are produced in a large-scale production or a small-scale. With large-scale production, piston rods will be forged, molded by powdered steel or sintered, whereas piston rods in small series will be cut off from solid metal pieces.
How forged connecting rods are made?
Forging is a manufacturing process involving tooling dies, extreme heat and pressure. The die is essentially a negative of the rod, similar to a mold. A blank piece of metal is heated to a temperature where it is malleable and then forced into the die using high pressure, often referred to as hammering.
Are connecting rods forged or cast?
Connecting rods are not universally made by forging. Only some OEMs actually used forged rods. And some OEMs may use forged rods only on higher performance versions of a given car or engine. Many connecting rods today are manufactured using cheaper methods such as casting or powdered metallurgy.
What material are connecting rods made from?
A connecting rod with a tension load is made of forged steel, cast steel, or fabricated steel. Rods with a compression loading are cast nodular steel or aluminum alloy.
What is engine connecting rod made of?
In mass-produced automotive engines, the connecting rods are most usually made of steel. In high performance applications, "billet" connecting rods can be used, which are machined out of a solid billet of metal, rather than being cast or forged.
How are powdered metal connecting rods made?
The new rods are made from sintered powder metal, a specialized mixture of metallic elements that is pressed and heated to form super-strong, lightweight parts. It's an alloy part, really, and sintering is the heating process that bonds the powdered elements together, but without melting them.
How long do titanium connecting rods last?
Titanium Connecting Rods
That comes with a price; titanium rods typically are typically four times the cost of a billet steel rod. The other drawback is that titanium rods do have a fatigue life in race applications and are typically switched out every 40-80 hours.
Why connecting rods are forged?
The strength of forged steel connecting rod is higher than powder metallurgy rod. Due to this the engine compression ratio increased. As a result, high strength of forged connecting rod became more satisfactory. This forging method could meet both the strict requirements of weight and size tolerance.
Are all connecting rods forged?
Most aftermarket steel connecting rods are made from forged steel. There are different types of forged steel based on the grade of material. ... For more highly modified competition applications, most manufacturers, including Eagle Specialties, utilize high-carbon 4340 or 4330 steel.
What is split type connecting rod?
A split type connecting rod is formed such that a large end portion is fractured and divided into a rod portion and a cap portion a long a splitting plane including the shaft center of a crank-pin hole, and the rod portion and the cap portion are coupled by coupling bolts, and a metal bearing is generally located on ...
Which material is best for connecting rods?
Steel is normally used for construction of automobile connecting rods because of its strength, durability, and lower cost.
Which steel is suitable for connecting rod?
cast iron is best material for connecting rod because a connecting rod is subjected to fluctuation and impact load so material need high fluctuating strength, Rigidity, and high damping factor which are cast iron properties..
Which carbon steel is used for connecting rod?
Low Carbon Steel (Mild Steel): Low carbon steel is an alloy of iron and carbon. The carbon content varies from 0.05 to 0.15 % for dead mild steel and 0.15 to 0.3 % for mild steel. The dead mild steel is very much ductile and is used for making various components like sheets, strips, wires, rods etc.
What is crankshaft material?
Crankshafts are made from forged steel or cast iron. Crankshafts for high-volume, low-load production vehicles are generally constructed from nodular cast iron, which has high strength (see Appendix D). Fuel-efficient engines require a high power-to-displacement ratio, which has increased the use of forged crankshafts.
What material are piston rings made of?
Piston rings are usually made of cast iron and steel. Wear resistance is an important requirement in the materials used for their manufacture.
